Its absolutely productive... Best Buy had a reason for blowing those out, probably a net down on older goods or something. Either way, BB had to get rid of them.
And you think end users wouldn't have bought them? All the really good BB deals I've seen they would have sold out quickly regardless of whether one reseller bought 20 or 20 individuals bought one. That expensive HTPC oriented keyboard comes to mind. BB lowered the price to something crazy, a hundred resellers snatched up most of them, thousands of would be end users got stiffed. Stuff like that is annoying, but the Wii thing is too much. Taking an item out of the hands of someone that can pay 250 for it and putting in the hands of someone that can pay 600 for it isn't something you should pat yourself on the back for.
Yes, what can you say?
I agree with your line of thinking. When there are big sales, it would be nice to see the savings passed onto the consumer instead of them being snatched up in bulk and re-sold at an inflated market value. Supply shocks are definitely responsible for the Wii's and how re-sellers have taken advantage of it.
I see re-selling a product with an inflated MSRP as more along the business models of Monster Cable and Bose but on a much smaller scale. There will always be desperate and uninformed consumers that will pay a premium on products.
