CompUSA has a “open box” return policy. If you open the box, then you can return it for cost – 15%. Or you can return it for a gift card for the full amount. So, in the process of returning my scanner (yes, I’ve completely given up on scanners for the moment) I discovered the way around this.

Step one. Purchase item
Step two. Return opened item and get gift card.
Step three. Purchase another item of similar cost.
Step four. Return this item unopened for cash value.

Don’t tell them I told you.
