Anyway, I'll be ungrumpy for once today, I suppose.
Bottle openers -
seriously. I read beer steins - also a good idea. Unless you're worried about offending parents, which you probably are (or Crave is, at least). Advertising pens can be pretty cheap by the 1k, and you could probably turn at least a 200% profit on trinkets such as pens, letter openers, pins, maybe even patches? Anything small and easy to put a logo on, y'know.... like those Nintendo 64/Mario 64 wristwatches that came out with the system. I'm sure people'd buy a 20 dollar GR wristwatch or something, but you never know, you could contact fossil and swatch, etc. and see how much for some classier looking ones, but still cheap none the less.
Do a few of your average round pins, or whatever the hell shape you want them, then do a set of pins (also like the Nintendo 64 pins, sorry, can't get my mind off that stuff now that I've thought about it). 4-6 in a cheap, transparent and collectible case with different color schemes, logos or whatever. (pr0tip:
only offer these pins as a set, forcing buyers [nagged parents] into a corner
)
Keyboards and mice, maybe. Gaming peripherals of all sorts. Shit, you could even have a black and red bluetooth headset. Go nuts! If it's within your budget and this site is getting a lot of traffic, then just push as much merch as you can when you can. I suppose it'll all depend on the store's revenue/popularity in the end, though, so there's really no need for me to make assumptions.
Sunglasses. Hats. Blah blah.
Hey, I'd buy a GR pocket protector! No joke, I would >.<
Along with the pens and other such bulk purchasing on your end, you could get binders for kids to feel too cool to go to school with. Backpacks, too. Lunch pails! WITH A MATCHING THERMOS!
Alright, I've had quite enough coffee today for one lifetime and I've given you quite enough bad investment ideas for a couple of lifetimes (insert women's lib joke). Time to get back to cursing at this absentee ballot and shaking my head; wouldn't want Arnie to get stuck here in the past or anything.
