SD cards were one of the few items where this happened with non-special SKUs. Off the top of my head, the only other product segment this happened with was cheapo TVs. Almost everything else, if there was a model ID mismatch, there was some indication that it was a "Best Buy-only" model (if only because of minor differences). The vast majority of products could be price matched with Amazon, and customers took advantage of it quite often. If you really want to see this strategy in action, try shopping for mattresses.
