Mail clubs basically became extinct after DVD's went all-sale-price and we all bought them through Amazon.
(Except for Disney Movie Club, which at least has some exclusive titles not sold retail...)
The CH Tape Club was a necessity, since they clearanced out old $99 rental tapes three months later for $29.95, and you could find just about anything that hadn't hit shelves yet--
But with every DVD affordable, someone didn't tell them the bad news that they couldn't do their old act for an encore, and we didn't need them nowadays.
