What decides the cheapest carrier
- Weight: under about 5 lb, USPS Ground Advantage is usually cheapest. Around 10 lb, UPS Ground Saver often wins.
- Box size: big, light boxes are priced by size, not just weight (called dimensional weight). In the 20 lb, 18×18×12 inch example, USPS costs almost three times as much as UPS or FedEx Ground.
- Distance: prices rise with distance, but not equally for every carrier, so the winner can change with the route.
- Speed: the cheapest options take 4 to 6 business days. Need it sooner? USPS Priority Mail and UPS 2nd Day Air are often the cheapest 2-day options; overnight costs much more with every carrier.
Online prices vs the counter
These are discounted online rates. Walking up to a carrier's counter usually costs more for the same service: in our October 2026 price check, a 5 lb UPS Ground box from Phoenix to Chicago was $58.61 at UPS retail and $16.24 on ShipGopher. See more examples.
