DO NOT BUY FROM THIS SELLER. IT'S BAD ENOUGH THAT AMAZON.COM ALLOWS THIS SELLER TO CONTINUE ON THEIR SITE. I RETURNED AN 8G EXTREME IV MEMORY CARD IN SEPTEMBER 2009 FOR A FULL REFUND OF $ 85.83 AND AS OF NOVEMBER 18, 2009, I HAVE NOT REC'D MY REFUND. IF YOU HAVE TO RETURN SOMETHING TO THIS SELLER, YOU WILL NOT BE REFUNDED SO KEEP THAT IN MIND IF YOU WANT TO TAKE A CHANCE WITH THIS COMPANY. I MAY NEVER BUY FROM AMAZON AGAIN SINCE THEY STILL ALLOW THIS COMPANY ON THEIR SITE. THIS IS THE FIRST TIME I HAVE EVER BEEN RIPPED OFF BY BUYING SOMETHING ON AMAZON.COM.
