ever bought an extra copy of a back issue by accident?
 

Recently earlier this month when i was out of town and went to a comic book shop, i accidently bought a copy of Adventures of Superman 510 since im trying to get certain back issues involving the Bizarro's World story arc in old Superman comics.

I find out I already have the old issue of Adventures of Superman 510 that still have ever since from back when i was in high school at the time.

Anyone else else accidently bought a copy of a back issue that you already have and you didnt know you already have?

Not the first time it happened to me. Even last year or so when I was trying to catch up on old Incredible Hulk comic with the Ghosts of the Past story arc. i ended up finding out that i bought an extra copy of an issue by accident.

My personal opinion there was just too many Superman comic books at the time back then in the mid 1990s involving certain story arcs such as Bizarro's World, Fall/Battle of Metropolis and the whole Death of Clark Kent + Conduit storyline

When I was trying to rebuild my Marvel GI JOE run I'd do that at comic shows. I'd always forget my list at home. But usually they were so cheap, like the 2 for a dollar box, that it didn't matter too much.
