It is weird, me and my friend saw a big bottle (those big containers that hold the sodas) of it at our school bookstore(with sodas in it), and were like, dnL?! Then we realised it was just upside down 7-up, and didn't really think about it. This was thursday. Then my friend sends me a link to this ebay stuff, and one guy is selling a single bottle of it for $10!!! Its supposed to be new this november, but we saw it on halloween. I think I'll pick up a few bottles at school and try to sell them on ebay too. My school has become cool... They also have started to sell bawls for $1.25 =D
In short, no I haven't tried it.
