Hasbro keeps using cheaper and cheaper factories... and since most regular kids probably wouldn't notice or care if a short-lived toy in their possession has two of the same hands or feet, Hasbro wouldn't really care if the small portion of dedicated collectors come across a defect. They know that we keep collecting the toys, and even if we were able to return them to a retailer (as most of us import now to save money or get the toys we missed), it becomes the retailer's problem, not Hasbro's.

This is why Hasbro is foolish to take on a quality company like Lego, as Lego is just way out of their league.
