This just goes to show that these video game shops are making their money off of used games and trading. As I've stated a few times throughout the years in these forums, I went to sell ebgames probably $600 (more or less) of sega cd games, at a time when they were still selling sega cd games in all of the toy and game stores, and I was only offered like $17 for them. These are pawn-shop strategies, making poor, innocent children think that they only pay a couple bucks for brand new games to their suppliers/distributors so that they can maximize their profits.
So, it sounds like anyone wanting to start a small mom and pop video game trading business would have to deal with either ripping people off, or taking a loss (after overhead) selling only new games.
I have tried twice to start a small video game business. The first time, I had a partner, and we sold mostly used, some new, and import games, as well as VCDS and other imported novelties, and we actually made money, as well as always having something new to tinker with (new games, systems coming in all the time,) but my business partner didn't think the money was coming in fast enough, and he wanted to waste all of the profits, and after a lot of fighting, I ended up just selling off my part of the business to my business partner.
We started off making around $1000 to $1500 each month profit, and had very little overhead, which I thought was a pretty good start for part time work.
The next video game business venture, I would get into a local market, less imported stuff, and newer consoles and games. There was just too much competition. Nothing sold, and places like best buy could sometimes sell stuff cheaper than I could acquire wholesale. So, I think that's my last bout with trying to start a video game business.
