What does "Free Shipping" Mean?

"Free Shipping" means that you will not be charged additional fees for the shipping of that product. However, unlike "Prime," which usually guarantees fast two-day shipping, "Free Shipping" doesn't necessarily mean fast shipping.

Sometimes there might be a minimum purchase requirement to qualify for free shipping if you are not a Prime member. For Prime members, the "Free Shipping" usually refers to the free two-day shipping that is one of the benefits of the Prime membership.
