find a walmart thats shutting down thier fish section snap upthier units and you will be one step ahead for stock wise. i just noticed that one of them just shut down thiers here in regina and i had bad thoughts go through my head that would make my wife kick me out. oh wait im a locksmith i can get back in .. but you get the idea
they may even give you the units n/c if you remove them and you ask nicely.
