The Amazon e-gift cards are easy to purchase and send to someone by e-mail, have no fees, and do not expire. People can buy virtually anything but prescription drugs with them. Because of the ease in purchasing and versatility, we have used these as personal gifts and to compensate US research participants for taking online research surveys. The main limitation of the Amazon gift cards is that some people do not shop online, and other people do not shop on Amazon. In particular, some gift recipients may object to Amazon’s well known and ethically questionable practices in employment (poor treatment of employees and contractors). You should make sure your gift recipients are OK with shopping on Amazon before choosing this product.
