Amazon Prime is one of Amazon’s biggest cash cows, and the free shipping the service offers is one of Prime’s biggest draws, so doesn’t it seem a little counter-intuitive for the company to start offering free shipping to non-Prime users? Well, that’s what it looks like on the surface, but Amazon’s new free shipping program is limited to just a few thousand products, with the requirement being that the product weigh less than eight ounces. This is to attract more budget-conscious shoppers.
