LOL Only time I had luck 'stashing' a guide, it was an original Oblivion guide and I put it on the usually empty bottom shelf in the PC game section. And, do you know, it sat there and sat there and sat there and sat there till it finally dropped.
I guess NO ONE, not even LP, looks THAT low down on the shelves for misplaced product. OR, if one version of a guide is about to drop and newer versions are already out and on the shelf, stash a copy or copies of the guide you want in with them.
That's how I found 5-6 more copies of the original Oblivion guide up in NY about a month or so ago, because they were dispersed between the other newer version copies.
As for my luck, back when I was going to Atlantic City regularly with my one ex gf for either day trips or an overnight, I would routinely stop at ONE prime location off of the PA Turnpike/Blue Route and that ONE store would regularly yield massive hauls for me.
Also, when we would hit a certain diner in NY state(Alexis Diner, or Alexi's, however it's spelled), I would make sure to hit another certain gold mine store up along Route 84, where I routinely would pull about 30-40 guides PER drop from on an average basis.
Both of these sources have become DRIER than the Mohave as of late though, one due to the presence of another CAG(who I won't mention, but have hung out with from time to time) and the other is either the store employees due dilligence or the work of yet another CAG.
As for my own LOCAL stores, I was told by my usual 'source' for confirmation of drops(even if they're already pulled), there is either a FWer, CAG or SDer who comes in whenever they have sales or guide drops and looks for anything and everything. SO, one of my own local stores is OUT, that's for sure, but the other one regularly surprises me with a missed or restocked guide here or there, but not as much as they once did.
I think, much like many others, that penny guides are coming to an end. Either that or the crackdown will eventually relax and stores will become lax again, but that's NOT looking like a good option right now.
