Flat Rate shipping means you pay a set fee to send a box of a certain size, no matter its weight. If you're sending a small, but heavy package, Flat Rate shipping could help you save considerably on your delivery.
You can send packages through your local USPS Post Office, using boxes in a variety of sizes, including small, medium, and large envelopes. Smaller boxes are generally cheaper, so choose the best size for your item in order to get the most out of the service.
"Flat Rate shipping takes around 1-3 business days," shipped with either USPS Priority Mail or Priority Mail Express. The time taken will ultimately depend on where the package is coming from, and where it is going. To get a better idea of how long delivery will take between US states, check the USPS Priority Mail Delivery Map.

Whilst Express services offer you the comfort of speed, they also come at a greater cost per parcel. If you're a seller that works with items of a similar size, you might value Flat Rate shipping for the consistency of delivery costs. Like most shipping services, there are benefits to both - it all just depends on your needs as a single sender, or a business!
