Purse.io: Amazon shopping at reduced price
While shopping from Amazon, one can do shopping at reduced price on Purse.io. This is because someone from other side is willing to convert his or her Amazon gift card into cash. In order to convert to cash, they are willing to sell their gift cards at discounted rate. So, you do shopping through their gift card balance and pay to them less than the amount you would actually pay by directly buying from Amazon.com through your own account.
Purse.io has the software and a pool of members who are willing to sell their Amazon gift card balance.
