You get seven days to figure out what’s a keeper, what’s a no, and to check out online. For the check out process, go to Amazon’s “Your Orders” section and indicate what’s being kept or returned (if you don’t do this before the end of your try-on period, your account will get auto-charged for the full order). The form will prompt you to select a reason for returns: “Not Needed,” “Too Small,” “Too Large,” etc. Perhaps tellingly, “Wrong Item” is one of the options, suggesting shipping orders aren’t always correct. (I had to put the “Wrong Item” button to use myself on a pair of jeans.) After you finish the checkout process, you’re charged for items you’ve kept.
