ioffer is complete fraud. do not use it. it is too good to be true. The sellers contact you in timely manner till they take your money and don't return your complaint emails. and they can continue to do business this way. most of them are overseas so there is not much you can do about it. as for using your visa for purchase protection, most of them don't take visa but only through paypal which makes it harder than ever to claim a dispute. it's like getting screwed twice.
all of these companies being an us company, i can not believe that they can do business this way.
I have seen similar things with paypal and Ebay. why is it that these companies are not held accountable??? it's fun and sometimes cheap to get auction items but i think i will stick to malls.
