yah so ive ordered from those guys a couple times because it's hard for me to find shisha where i live, i have to get my girlfriend to send it from DC and shit.
anyway, that site is legit, they have pretty cheap stuff cause it's mostly wholesale, and they'll sell you a pretty good sampler combo for cheap. CHECK IT! WORD!
if you order a bunch of the little boxes though only open one or two at a time, they dry out really fast if you dont use them up, and dry shisha just plain hurts. dont try putting it in the fridge either, that dries it faster than anything.
