selling $90 voucher

hi, i preordered stacraft 2 months ago on cdwow.us yet they still have not delivered, i want to cancel the preorder but the only option they give me is a voucher for the price i payed, since i hate the website and i dont plan on buyng there again i was wondering if someone was interested in the voucher to trade/buy it(apparently they are havcing problems with theyr suppliers to buy in large quantitys)
