The simplest rule of marketing suggests that there always has to be a hook. If you're looking to get people to shell out their money, you need to make sure they're getting something special in return. Unfortunately, that leads to cynical cash grabs designed to part patrons with their hard-earned at the expense of integrity and occasionally logic.
With comic books, there have been some stunning strategies employed to double down on sales, with some working better than others. That's the reason behind endless events, crossovers and variants, which have their value, but it's also why fans have had to endure some ridiculous sales gimmicks over the years.
