That sucks. I try to get my stuff from the shop in my town because I want him to stick around. His store is growing, which is a good sign, but I doubt that it's a high profit business. I think that the Magic, and DnD people keep those shops open.
They do. The money is in Magic, YuGiOh, D&D Adventurer's League, etc. It's what keeps shops open. Very few comics only shops around anymore, while lots of game only shops are doing ok.
