if you'd rather just pick one up and if you in philly there's wonderland on 20th and walnut - but they are wayyy overpriced and its an uncomfortable atmosphere - have your ID ready when you walk in... then theres another one called artifax up in the northeast which is known for being much better on prices..a boy of mine got a bubbler there and hes kinda of happy with it, but i know there much better than wonderland
you could always find a local illadelph dealer too, i've run into a bunch and they sell you there shit direct from warehouse and show you stuff in these metal cases....really nice stuff
but back to your original question - bongs are LEGAL (for tobacco use**)... so dont worry about ordering one dude
