Factors That Affect Price
Distance and class of service are primary price drivers; longer distances and stricter delivery windows raise costs. Weight and size of the box also influence the final amount, especially for non-flat-rate options.
Other drivers include insurance value, add-ons like signature required, and regional surcharge eligibility. Volume discounts or business accounts can reduce per-shipment costs on multiple boxes.
Ways To Save
Choose flat-rate options when possible to lock in a price that does not depend on weight or distance for eligible boxes. For light, compact items, flat-rate small or medium boxes often offer better value.
Consider bundling shipments with a business account or using periodic promotions to reduce average costs per shipment. If delivery speed is flexible, opting for a less expensive service level or delaying to a non-peak time can yield savings.
