what does flat rate mean for shipping

what does flat rate mean for shipping Flat rate shipping means that the cost of shipping is fixed regardless of the weight or destination of the package, as long as it fits within a specific box or envelope size. This pricing model makes it easier for customers and businesses to calculate shipping costs in advance. USPS, UPS, and other carriers offer flat-rate shipping services, which are particularly beneficial for sending heavy items, as the shipping fee is not influenced by weight or distance, only the size of the packaging.
