mrmopar hits it on the head, it's one thing to have a limited redemption period tied to a call up, it's another to say that certain signers are in the product and you only find out after opening a box that the item you have is a redemption for a certain time period. This gets into the realm of expired "gift cards" or "redemption fees" that certain states like California have cracked down on and won judgement aainst as unfair business practice. Some state's Attorney General will nail one of these manufacturers and the precident will be set, at least to a point that if they want to sell product in that state they will have to comply.
