This is more of a gripe, but I was wondering if anyone else has noticed this. Looking at the PF63 and PF64 equivalents sold at Walmart, I find myself looking at their pricing and kind of agreeing with them, since Walmart's prices tend to mirror the market in general or do better (i.e. lower price) for nearly any item. The only notable exception I've seen and keep seeing is the Wix XP. They tend to run around $21-$22 each. Any idea why the Wix XP commands such a premium at Walmart?
