As someone who's been in that store on numerous occasions, I can tell you the their stock on Neo Stuff is extremely liquid. It comes and goes at alarming speed. I've gone and seen one game on one day, then seen dozens on another. The quality of the games is all over the place (since they buy them used).
The sad thing is there are plenty of saps out there still selling them their games at those unbelievably low prices. Sonofx51 and I joked about staking out in front of the store and buying those games off of the people going to sell them:

Shady Bobak: Hey.
Naive Customer: Who... me?
Shady Bobak: Yeah, whatchoo got?
Naive Customer: What?
Shady Bobak: Whatchoo got there?
Naive Customer: Oh, you mean this game? Oh, I'm just planning to sell it to GameDude in order to finance my new X-Box.
Shady Bobak: You don't wanna to sell it to them.
Naive Customer: I don't?
Shady Bobak: Naw.
Naive Customer: Well, then what? I need the money.
Shady Bobak: Hmm. Let me see what it is.
Naive Customer: See?
Shady Bobak: Oh, a Neo Geo game, huh?
Naive Customer: Yeah, I know. It's a dead system -I don't know anyone who has one. That's why I'm selling it here -they're the only people I know who'd buy one.
Shady Bobak: Well, let me see... I might be interested in buying it off you.
Naive Customer: Really?
Shady Bobak: Yeah, I've been kinda interested in getting started into the Neo Geo shit. I got a system the other day.
Naive Customer: Well golly gee, mister, you better know that there's no games anywhere for it. I only found this by accident in an EGM ad years ago.
Shady Bobak: Yeah, maybe you're right. But I think I'll give it a small whirl and see what I think.
Naive Customer: So you'll buy it off of me?
Shady Bobak: Yeah. Let's see, I got the GameDude price guide right here... Hmm. Metal slug... Metal slug...
Naive Customer: Wow! They'll give me $150 for it?! Awesome, that's only $50 less than I bought it for!
Shady Bobak: You're right, chief. That's a good price. I dunno, though. I really am interested in the game... I'll tell you what. If I pay you 175 cash, would you consider parting with it? I promise I'll take good care of it. I got the cash right here:
Naive Customer: Wow! $175??? Sold! Thanks Mister!
Shady Bobak: Here kid, have my pager number. Next time you're thinking of unloading some Neo merchandise, just give me a buzz. I'll hook you up.
Naive Customer: Oh yeah, you bet. Thanks again!
Shady Bobak: Not problem, kid. Have a nice day.
