On 22 October I ordered Windows 7 from Sam's.com because it was cheaper than on the shelf item. On 4 November I was told the order was canceled by Sam's because they couldn't get it from vendor, it is no longer on the shelf at Sam's. It IS still on the shelf at WalMart. They wouldn't even offer a price match voucher to be used when it became available again. I had NO TROUBLE ordering it from another Internet Merchant and getting it in 2 days. I'll never buy anything from Sam's.com again. read full review »
