Excellent comment ! Here here !not that its not fun to rip on pet stores and stuff (most of them diserve it) but you guys have such a problom with it then why dont you get a part time job at one?
just grabing the tarantulas they have and splitting to never go back there again dosent solve much of a problom... talking to interested employees and asking if they want to learn a thing or two is probrably a better route
