Saving 20% of amazon cards buying with BTC, is that on the forum? Sounds dodgey to me and if I was OP I would want something safer
Sounds like scam, written all over it.
Anyway if someone CAN give so much discount for paying with bitcoin, its huge success for bitcoin
Purse.io is not a scam, they are legitimate.
The way it works is that people who want to buy/obtain bitcoins will instead buy the goods off Amazon for you, and receive the bitcoins as payment. Everyone's happy, you get your product and they get their bitcoins. It's not always a 20% discount, usually it's closer to around 10-15%.
Of course, you can still get scammed by an individual seller, but the purse.io system isn't a scam.
