That's so not true.
If you walk up with 1 guide, he might just let it slide. If you walk up with 100, it's probably a no go.
Even best buy managers can detect obnoxious greed when they see it.
The last guide I got might have been Dragon Age 2. There were 20 guides on the shelf. It rang up as "cannot sell" or whatever. Since I only had one, the manager just said "take it."
If I had taken all 20, I doubt he'd have let me take it.
Remember though, it used to be clean ... they would ring up as $0.01 and that's what you paid. The new way they're ringing up red alerts that they're no supposed to be sold.
It was good while it lasted - this is the end of penny guides for me!
