Of course everyone who frequents the Raven will buy them, because we're die-hard Indy fans. Indiana Jones is one of the most successful film franchises of all time, though, because every average Joe loves Indiana Jones, even if he's not a die-harder.
No male on earth doesn't like Indiana Jones, and I'd speculate that most women like the films just as much. These are people who'd buy the Indy trilogy, but wouldn't really get into the whole YIJC series. No way possible that the YIJC set could come close to matching the original trilogy in sales. No way. Period.
