Query: Beware of seller!

I bought 2 of these 4GB sd cards. I opened up the package and immediately placed the cards in the reader. One of them worked fine, the other was DOA. I placed the card in my reader and it told me that the card needed to be formatted and that it has a capacity of 32MB!! I emailed the seller that I wanted a replacement card sent to me and once I received the card I would send them back the defective one. I got an email stating that I must return the card for them to test, and if they found it defective then they would send me a replacement if one was available! You do get what you pay for. BAD BUSINESS! STAY AWAY!!!!!!
