I have 3 Wal-Marts within 10 miles of my house, and all of them have gotten rid of their locking glass cases for their games within the past year or 2. I guess your Wal-Mart just hasn't been remodeled yet. By pointing out that the display copy is NOT used, period, you're supporting UncleBob's argument. Normally you can return unopened software at just about any retailer (including GameStop) for a full refund, or at least full credit - but if you buy the display copy, it's already opened, and GameStop will only buy it back as used and give you less money than you paid, because it's not sealed, but as you pointed out, being the display copy doesn't mean the game has actually been used.
