I am going to Beijing for 4 weeks this summer as well. haha. I'm bringing juice and mods and attys with me, but it'd be fun to find a vape-shop, and it'd be great to find some cheep clones. I figure there will be some vendors selling vape stuff at the Silk-Market or the Ya-Shao market. Those are the go-to places for cheep shopping. Tons of counterfiets, and tons of not-counterfiets. You've just gotta sift through some of the crap and barter for a good price. If you're western, they will try to rip you off really hard. Like, take a pare of Nikies. They would be over $100 in the states, so the chinese vendor will ask you for $100. If you are Chinese they will give you their real price which is more like $30, but you should be able to get them down to $10. I always come back with mass $10 shoes. If they wanna rip you off, just walk to the next booth and they'll have the same stuff. Shopping in Beijing is awesome. It'd be awesome to find vape stuff!
