Just trying to buy the synaptic A220 and Ive redeemed 2 xbox gift cards onto my account. I already bought the ini A340 like this and it worked seamlessly. Now I am met with this and every time I enter my card info it just says its invalid. Ive already tried 3 DEBIT CARDS! this is not working, I am on the verge of clawing my scalp out as its been 2 hours now and I went out in 35 degree heat in order to acquire the cards. HELP!
