> For the people who buy one of each color and then return all but one

Amazon's "try before you buy" encourages people to do just this, so I'm guessing Amazon has figured out how to make this shopping pattern profitable.

Try before you buy is not quite the same as buy a spread in order to pick one.

Actually in this case it is, you choose a box of items to get shipped to you and ship back what you don’t want. You can get an identical shirt in 5 different colors, or sizes, and ship back all but one.
