I would just beware of anyone touting an one or two particular figures as being super rare or hard to find... not saying that if they claim that that they are lying. They may actually have some really good figures (or not).
Otherwise if you are paying on average 50 - 75 cents each for the lot, you are are probably doing pretty well and getting a good deal.
If they are specific in what they have as being particularly pricey... then just research that particular figure, yknow?
Hell, even if you buy a big lot and you get a few bootlegs in the mix, that may not actually be a bad thing as there are plenty of collectors that will go out of their way for bootlegs. You just don't want to pony up big money for a particular fig and then discover it's bootlegged, if that makes sense.
Good luck with your purchase.
