buy everything online, going to stores can be a bit shady cuz the owners can either overprice things, have an off-brand hookah that looks close to the real thing, or be completely legit. so you have a better chance at getting something thats good quality and right price if you shop online. here are some websites that recommend.
buy everything from here, great prices and customer support)
you might find something close to what your friend has found or something even better. hope this helps and good luck
