Collectors have heard the stories of someone breaking a box, or perhaps a case, and getting a redemption card (s) which has expired. Some get nothing in return, while others might get a different player of 'like-value'. Whatever the case may be, it's certainly been a controversial subject in the hobby.
One company in the past didn't have a problem sending out cards to the collectors who requested them. According to the Standard Catalog of Baseball Cards, the 1954 Red Heart Dog Food cards, produced by the Red Heart Dog Food, Co., were still being sent out to collectors who requested them as late as the early 1970s.

The thirty-three card set consisted of three 11-card series, each of which had either a red, blue, or green background. The red series is the more scarce of the three. Each of the series were available through a mail-in offer-all collectors needed to acquire a set were two dog food labels and ten cents. Imagine that: a Mantle or Musial for such a small sum! It would have been quite the acquisition, as neither were included in the Bowman or Topps sets that year.
If it is true that sets could still be obtained from the company during the early 70's (and there's at least one person who claims it's a false rumor), then today's card companies can certainly learn a thing or two about customer relations and honor such said cards. And in case you missed it, one collector from Michigan recently won his suit vs. Upper Deck over expired redemption cards. You can read it here.
