like i don't see them stapling together two random comics just to sell them, but. maybe that's what happened
and i don't see myself having bought two separate comics in 2006 (?)
plus i can't see a grocery store carrying single issues comics, especially with one being from 2003

i know that the ultimate spider-man issue was one of the venom arc issues, because i saw venom and was drawn to the comic because of it
and i know that the power pack comic was a crossover comic between the x-men, because i remember wolverine being in it
