There is some services where you could use bitcoin for amazone and some other online and offline stores.
Your OP is not so clear what actually you want? of what actually are you offering?
il buy whatever you need with my amazon account for BTC! plus il take lower offers since the btc price could always skyrocket! so basically im buying you stuff off amazon for a lower price and taking a risk that the price will go back up
Why we use your service and what will be the security for our btc?
By the way how much price you offer for a btc while buying products of amazon?
well we can use an escrow, and also il use the current preev rates at time of trade
If we have trusted company with a huge amount of trading experience and fast services there is no point to choose your services.
May be if you have some special like Cheap product then Amazone or Highest Price for BTC then that was fine if now there is no any point to use your services.
By the way i do use my BTC for Amazone, Walmart, Staples and other various website from
