priority mail vs flat rate

priority mail vs flat rate compares two different services offered by USPS for sending packages. Priority Mail is based on weight and size, with pricing that depends on how heavy the package is and how far it needs to travel. In contrast, Priority Mail Flat Rate offers a fixed price regardless of weight (up to a certain limit) as long as the package fits within the provided flat-rate boxes or envelopes. Flat Rate is ideal for heavier items, as the cost remains the same regardless of weight. Priority Mail offers more flexibility for lighter packages or items that don’t fit in flat-rate boxes.
