The guide
Each step in the order you'll need it.
Weight decides most of it
Ground Advantage prices by weight and distance, with the cheapest tiers for packages under 1 lb. That covers most clothing, cards, jewelry and small toys a home seller ships.
Past about 5 lb, rates bought through a label tool come in under USPS. Weigh the packed box and compare both before you buy the label.
Kit for this step
Size and dimensional weight
UPS prices most boxes by dimensional weight: a large, light box costs as if it were heavier. USPS applies the same idea only to larger packages.
Use the smallest box that fits the item with padding. A snug box keeps you on actual weight with either carrier.
Kit for this step
Buying labels at the right price
The counter price at the post office or The UPS Store costs the most. eBay labels, Pirate Ship and USPS Click-N-Ship sell labels at lower commercial rates.
Platforms with fixed labels, like Poshmark, pick the carrier for you. On eBay, Etsy and Mercari you compare USPS and UPS on each order.
Drop-off and pickup
USPS Package Pickup is free when you schedule it online with a prepaid label. Packages leave from your porch on your mail carrier's round.
UPS charges for on-demand pickup. Drop-off at an Access Point in a pharmacy or convenience store is free and open later than a post office.
