ChengduCha, I have been in touch with the YS folks, since they have a gaiwan I want.
They haven't gotten back to me with a shipping quote though.
Scott sometimes takes a day or two to respond, you can also see the shipping costs upon checkout when you choose HK as your shipping country.
It'll change from the standard international shipping rate of $20 or so to the real one that'll apply to you.
Some of their tea appears to cost much more than on Taobao, and other items cost less, so it pays to compare IMO.
If you want lots of samples to broaden your taste they're the best imo, especially when you want to see what cakes that are way out of your price range actually taste like in comparison to what you already know.
I have big trust issues when it comes to anything consumable from Taobao
, but I'll probably try a manufacturer tmall store or two in the near future.
