Hi as the title says i want 6 bitmain coupons...pm me with offers...
You should go to Digital goods if you are going to buy 6 bitmain coupons. Try looking there if there is someone who sell bitmain coupons that you are looking for. This is the link of the board I mentioned
https://bitcointalk.org/index.php?board=93.0. Just be careful if you are buying coupons in person to person transaction or use escrow if you want to be safe.
