I need to buy bing voucher for above $300 (I can get about $300-350 myself). All sellers who come to me in skype offering vouchers of $600 (and sometimes up to $1500 lol!) ALWAYS disappear once I ask if they have feedback, or are willing to go first. If you are a seller, and you are sure what you sell works, I can even go with escrow and cover the fees. Let me know what you can do for me.
