Amazon's Prime Exclusive phones have great prices, but there was a big catch. You had to allow ads on your home screen and if you changed your mind later, it could cost up to $50 to opt out. Buyers got a bonus last week when Amazon decided to eliminate the ads, saying they could interfere with facial recognition and cause other issues. That's great, but it what about folks who paid the fee to get rid of them? Amazon has agreed to refund it in the form of a gift card, essentially closing the chapter on its Prime Exclusive phone ad experiment.
