So I signed up for Best Buy's GCU for the first time, and I have the B2G1 pre-owned coupon to use by the end of the month. The game guide coupon & the $5 off coupon shouldn't be a problem to use, but... is there anything actually good to use this on? Or some way to get around "in-store only" limitations?

I've looked at probably 20 or so games I might be interested in, and all of them say "there is no stock within 250 miles of your location". I actually even went to two stores, and from what I could tell there were no used games at all. For any system. They did have the "$20 value" games, but I didn't see a single pre-owned game.
Actually, when you look at pre-owned games on the site, and use the "pick up today" tab, there are 0-1 pre-owned games of any system available at the 8 or so Best Buys that are nearby-to-somewhat-far from here. And all are either wrong system or I'm not interested. (Someone who asked another associate for me said something about they'd all been "pulled"?)

I'm aware that ultimately it'll still be dependent on stock around me, but if there IS no stock... is the coupon basically worthless? The coupon states you can't use it on online purchases, including store ship/pickup. Any way to avoid that? The website has used games I want, but there's nothing in store I can use the deal on.

Just looking for tips from people more versed in BB, I've always been a Gamestop/Gohastings/Gamefly gamer.
