Amazon will allow you to refund accessories for the Samsung Galaxy Note 7
It is easy to forget that each popular handset supports many different companies that produce cases, wireless charger docks and more. Now, these firms are going to lose a ton of profits. That is the result of Sammy's decision to shut down the use, sales and production of all "recalled" and "replacement" Galaxy Note 7 units.
If you purchased accessories for your Galaxy Note 7 from Amazon, you need to give them a call to initiate the return process. You shouldn't have a problem getting your money back. One Amazon rep reportedly said that in most cases, Amazon's Galaxy Note 7 return policy also covers accessories.
