I haven't ordered from FT, but I'm about to place an order with a vapeshop in Hong Kong, which is probably similar in terms of shipping time. What I have heard is: if you REALLY NEED it, don't order from ____ (someplace on the other side of the planet)... if it's something you'd like to have, but without any time pressure, then definitely take advantage of the low prices wherever you find 'em.
The order I'm placing is for an eGo-C Twist 1300 -- for a backup battery, since I use iTaste vv3 and love it dearly. Also a carto tank, since I'm JUST getting into cartos, plan to play with them "on their own" for a while, so if it's 2-3 wks till I get the carto tank and pre-punched cartos for it, no biggie, and the prices on ALL those items are just un-freaking-believable. However I'm ordering a 2nd vv3 battery from a place in Arizona, because I know that even with regular 1st class mail, I'll get it within a week, which is fine, it's for backup also.
