Apparently, Amazon will cancel your account if you keep doing this

Fond of ordering the odd thing or two from Amazon?

So are we. You can get everything and anything on the site... however, if you do this one thing, the website will notice, and they will terminate your account. According to the Wall Street Journal, if the folks in Amazon HQ notice that you return a lot of the items you buy, they will shut down your account. “We want everyone to be able to use Amazon, but there are rare occasions where someone abuses our services over an extended period of time,” an Amazon spokesman said. “We never take these decisions lightly, but with over 300 million customers around the world, we take action when appropriate to protect the experience for all our customers.” However, many have noticed that Amazon won't inform you if they close your account, which has left many people up in the air about why their accounts were cancelled. But the Amazon spokesperson added, “the company says in its conditions of use that it reserves the right to terminate accounts in its sole discretion.” So, the moral of the story is - don't be pesky with your returns. Be sound and they won't shut down your account.
