I don't know. It seems good to have merchandise but that's where the problem starts, it would not appeal to real life people. It's like when I go into a store and see DVDs of a tv show I've never heard of and neither has anyone else. If I was really interested I would leave the store, go research the tv show, see where I could watch it and come to a conclusion whether I like it or not.
Also I didn't catch what you would be selling. I would leave this for a year or two, get more money in that sea of cash you have and ask again and see if this site has more notoriety.
I would prefer it if you could include more merch on here as I'm sure most people like the idea of buying it at the internet rather than looking all through the shopping centre.

I like the idea of a NG store, I'd love a place to go and buy something different or weird without having to go to something like Hot Topic(Which really is just playing off the goth fad more and more).
Also, the first thing that comes to mind when I hear about a newgrounds store, is DVD's. Not main stream, but flash from the site, maybe making a DVD of the best flash from the previous two weeks? Or just some awesome flash from the history of newgrounds. This could draw attention to newgrounds, and maybe some individual artists. I defiantly see more people showing off DVD's of flash, rather than going to some website to show it off.
Though, I'd hope to see the DVD's on the website if that ever went into action. Living in Alaska, I'd never be able to get down there and buy them from the store. Of course, I'm not sure how well they'd sell on newgrounds, since you can just go watch the flash on the website. Maybe contact some of the better artists to do longer flashes for a newgrounds DVD? Anyway, that's just something I always thought would be cool.
