The graffiti shop is a pretty awesome little cultural spot in Tempe. Located in a hard-to-find place right on Mill (you have to find the waterfall cul-de-sac, then go from there), it's worth it to check it out. They have a lot of smoking paraphenelia (i am not a smoker) but also other things local artists made like clothing and accessories. It's a bit more pricey but it's because most of the stuff is locally made. Also you can draw on the walls and stuff! Also a great place to buy tickets for concerts, raves, etc!
