Oh good! I just bought some DK-Tab to try -- didn't want to pay the shipping for Heathcabin, so I bought it from Valley Vapor. I guess it probably still is cheaper from Heathcabin -- 10 ml from Valley was 4.25, shipping was $1.71 for 4 bottles. Tried an interesting sounding Dekang, too. Chinese Wolfberry, whatever that is!
Vapor Valley - 20.71 for four 10 ml bottles including shipping.
Heathcabin would be - 23.71 for four 10 ml bottles. 1.96 a bottle, so 7.84 plus 16.00 for shipping.
I guess you have to have a big order for Healthcabin to be worth it. Over a certain amount shipping is free
