Prime Wardrobe
This is an interesting and underused part of Prime that basically allows you to try on clothes through the mail before buying them. If you’ve used similar services in the past, then you know how this works. You get a week to experiment with certain qualifying clothes, and within that time period, you can return the item for free. Otherwise, your account is charged. It’s an easy option for those who are worried about buying clothing sight unseen, but it only applies to certain clothing.
