The first time you sell something online that needs shipping, panic might set in. How do you pack it? Which shipping company is cheapest? What if it arrives broken? Who pays for shipping? Suddenly that $30 sale feels complicated and overwhelming.
Here's the truth: shipping is simpler than it seems once you understand the basics. Thousands of people ship items daily without drama, and you can too. Let's break down everything you need to know about packing, shipping carriers, costs, and handling the occasional problem so you can confidently ship items anywhere.

The Confidence Factor
Don't buy expensive shipping supplies from shipping stores. You'll pay 5-10 times more than necessary. Smart resellers source supplies cheaply or free.
Free boxes are everywhere if you know where to look. USPS provides free Priority Mail boxes in various sizes – order them online at usps.com and they'll deliver to your door. Liquor stores, grocery stores, and big-box retailers often have sturdy boxes they're throwing away anyway. Ask nicely and most will let you take them.
Buy bubble wrap, packing paper, and tape in bulk from Amazon, Walmart, or dollar stores. A large roll of bubble wrap costs $15-20 and lasts for dozens of shipments. Don't buy individual sheets from shipping stores for $5 each.
Save packaging materials from items you receive. Reuse bubble wrap, packing paper, air pillows, and boxes. There's zero shame in reusing materials – it's smart and environmentally friendly.
Keep a shipping supply stash organized in one area. Stock various box sizes, bubble wrap, packing tape, scissors, and markers. Having supplies ready makes shipping quick instead of requiring a trip to the store for every sale.
Invest in a good tape dispenser and quality packing tape. Cheap tape fails and boxes open during shipping. Spend $5 on good tape that actually seals packages securely.
Accurate measurements and weights determine shipping costs. Get these wrong and you'll either overpay or underpay (which causes problems).
Buy a digital shipping scale – they cost $20-30 and pay for themselves quickly. Kitchen scales work for items under 10 pounds, but dedicated shipping scales handle larger packages and are more accurate.
Measure packages at their longest, widest, and tallest points including any bulges or protrusions. Shipping companies charge based on dimensional weight for larger packages, so accurate measurements matter.
For dimensional weight, multiply length × width × height (in inches), then divide by 139 for USPS or 166 for FedEx/UPS. If this number is higher than actual weight, you'll be charged for the dimensional weight.
Weigh packages with all packing materials and boxes included. The final shipping weight includes everything, not just the item itself.
Round up to the next ounce or pound when entering shipping information. It's better to slightly overestimate than underestimate and face additional charges.
Each carrier has strengths and weaknesses. Choosing the right one saves money and ensures reliable delivery.
USPS (United States Postal Service) is usually cheapest for lightweight packages under 5 pounds and smaller boxes. Priority Mail includes free boxes and typically delivers in 2-3 days. First Class Package is the cheapest option for items under 16 ounces. USPS delivers to every address including PO boxes and remote areas where other carriers charge extra.
USPS also offers flat-rate boxes where you can ship anything that fits for one price regardless of weight. These are fantastic for heavy, small items like books or tools.
UPS often wins for medium to large packages over 5 pounds, especially to commercial addresses. Their ground service is reliable and reasonably priced. UPS pickup service is convenient if you ship frequently – they'll come to your house.
UPS is better for valuable items since their tracking and insurance options are more robust than USPS.
FedEx competes with UPS for larger packages and often offers good rates for overnight or 2-day shipping. FedEx Ground handles large, heavy items well.
Compare rates for each shipment using online calculators. The cheapest option varies based on size, weight, destination, and speed required.
Fragile items need extra care. Proper packing prevents damage and unhappy buyers.
Use new, sturdy boxes for fragile items. Don't reuse boxes that are worn, crushed, or weak. Double-boxing works well for very fragile items – pack the item in one box, then place that box inside a larger box with padding between them.
Wrap fragile items individually in bubble wrap with at least 2-3 layers. Secure bubble wrap with tape so it doesn't unwrap during shipping. For glassware or ceramics, wrap multiple times and consider wrapping in packing paper first, then bubble wrap.
Fill empty spaces in boxes completely. Items shouldn't move when you shake the box. Use bubble wrap, packing paper, biodegradable foam peanuts, or even crumpled newspaper to fill gaps and prevent shifting.
Mark packages "FRAGILE" on all sides in large letters. While carriers don't guarantee special handling, it can't hurt and may prompt more careful treatment.
Test your packing by gently shaking the sealed box. If you hear or feel movement, add more padding. The item should be suspended in protective material, not touching box sides.
For electronics, use anti-static bubble wrap and include original boxes when possible. Remove batteries before shipping. Take photos of working items before packing as proof of condition.
Decide upfront whether you're offering free shipping (you pay) or charging buyers for shipping costs.
Free shipping often attracts more buyers and leads to faster sales. Build shipping costs into your item price. If something costs you $8 to ship, price the item $8 higher and advertise free shipping.
Buyer pays shipping is transparent and protects you from unexpected costs, but can deter some buyers. Always calculate exact shipping costs before listing items. Use USPS.com, UPS.com, or FedEx.com calculators with accurate weights and dimensions.
For platforms like eBay or Poshmark, use their calculated shipping tools that charge buyers exact shipping costs based on their location.
Never guess at shipping costs. Underestimating loses you money, while overestimating angers buyers who feel overcharged.
Consider offering combined shipping discounts when buyers purchase multiple items. This encourages larger purchases while saving everyone money.
Print shipping labels at home using carrier websites or selling platforms. This is cheaper than paying retail rates at shipping stores and saves time.
Most selling platforms (eBay, Poshmark, Mercari) offer discounted shipping labels through their systems. Use these – rates are often 30-50% cheaper than retail.
For USPS, you can schedule free package pickup from your house when printing labels online. They'll grab packages from your mailbox or porch, saving trips to the post office.
UPS and FedEx offer drop-off at numerous locations including many drugstores, office supply stores, and dedicated shipping centers. Find convenient drop-off locations using their website tools.
Always get tracking numbers and save them. Send tracking information to buyers promptly. Most platforms do this automatically, but if shipping independently, email buyers their tracking numbers.
Despite your best efforts, sometimes packages get damaged or lost during shipping. Here's how to handle it.
Always purchase insurance for valuable items over $100. USPS includes $50-100 insurance with Priority Mail, but buy extra coverage for expensive items. Insurance costs a few dollars but protects against total loss.
If a buyer reports damage, request photos immediately. Assess whether damage occurred during shipping (your packing problem) or was pre-existing.
File claims quickly with carriers. USPS, UPS, and FedEx all have online claim processes. You'll need proof of value (receipt, listing screenshots), photos of damage, and original packaging.
For lost packages, wait the required time period (usually 7-15 days past expected delivery) before filing claims. Many "lost" packages eventually appear.
Save all packing materials from damaged shipments. Carriers often want to inspect packaging as part of claims processes.
Communicate with buyers throughout claim processes. Most buyers are understanding if you're responsive and working to resolve issues.
Create a shipping routine that makes the process quick and painless. Designate a packing area in your home with all supplies within reach.
Pack items immediately after sales. Don't let items sit for days waiting to be shipped. Quick shipping leads to better reviews and happy buyers.
Batch your shipping when possible. Pack multiple items at once, print labels together, and drop everything off in one trip. This saves time and mental energy.
Keep detailed records of shipping costs for different item types and destinations. Over time, you'll develop intuition for shipping costs and can estimate quickly.
Build shipping costs and time into your selling strategy from the start. Factor shipping when pricing items, and be realistic about how much time packing and shipping requires.
Here's what mastering shipping really gives you: the ability to sell to anyone, anywhere. No longer limited to local pickup, you can access buyers nationwide who'll pay premium prices for items locals don't want.
Shipping seems intimidating until you've done it a few times. After shipping 5-10 items, it becomes routine. You'll develop your own systems, know which carriers work best for your typical items, and pack efficiently without overthinking it.
Start small if you're nervous. Ship a few inexpensive items to practice before tackling expensive or fragile pieces. Each successful shipment builds confidence and competence. Before long, shipping becomes just another simple step in your reselling process instead of a scary obstacle!
