You can buy @ bestbuy and return it back if not good for your drive, full refund. I just asked the staf in the return/refund section, she said: “you can use only one of the blank in the spindle, and if it’s not good you may return them for a refund.” I reconfirm the word “use”, and she said you can burn or just check it.
With this policy, you should be careful buying media @ bestbuy. I’m guessing they repackage it. I found the other day, when I was looking at Verbatim 8x DVD+R 50 pack on sale for 29.99, there are three left. One of them uses cheap thin plastic seal that covers the entire spindle, and there are 3 rings floating on the top and if you turn the spindle up side down, the media will move. The other two have thick plastic seal that covers only some of the bottom and the wall of spindle.
