Yeah I think they have 30 days to say something is wrong with it lol. Imagine them mining with several cards for a month and returning them all .. they pocket several hundred dollars.
I am starting to feel I am stuck with these cards. I just offered to sell for $550 on local craigslist. Hopefully someone will buy.
you could sell them on amazon. i think amazon takes a bigger cut, but with the exorbitant prices and proper price range for your card, itll go quick. if i were you, id stick them in a corner with SMOS, and forget about it. let that shit print your ticket to the moon.
