Flat rate shipping means you pay a set fee for sending a box of a certain size, no matter how heavy it is, so if you are sending a small but heavy item, flat rate shipping could provide a significant cost saving.
You can send items at flat rate prices through your local USPS Post Office, where you can pick up flat rate boxes of various sizes, including small, medium and large and flat rate envelopes in a variety of sizes. Smaller boxes are generally cheaper, so make sure you choose the correct size of box to get the best value for money.
Alternatively, if you don’t have time to go to the Post Office, you can book discounted USPS services online with Parcel Monkey. Simply enter the dimensions of your parcel into the Parcel Monkey shipping calculator for an accurate quote.
