In other incredibly bone-headed moves: Best Buy has comparison shopper arrested. Yeah, okay. I mean, there's two courses of action here:

1. Throw out comparison shoppers. In this case, you have zero chance of selling to the shopper, since they're not even in your store any more.
2. Don't throw out comparison shoppers. In this case, there's a chance the shopper will discover a lower price elsewhere, and a chance they will not. Which means there's a chance you'll sell to the shopper.

Call me crazy, but if I'm a retailer I'd at least like a chance to sell to the shopper.
