The mark ups can be crazy. I get temple of heaven gunpoweder for like 8
bucks for 500G at my local asian market. That's about 1/3 of what upton
sells it for I think.

OTOH, it could be inferior tea. Proof of the pudding is in the tasting.
Brew some up, see if you like it, and figure you didn't lose to much if
it isn't good (and gained a ton if it is)
