You can ask for any sample (even the new flavors.) I asked for a repeat of Freckled Lemonade (which isn't out yet) and I got it, course, now I am noticing that lemony flavor make my throat hurt ::sigh::
I asked for a Freckled Lemonade sample after reading about it here. Totally got one with a handwritten label, and it's wonderful.
Most of the time, I want to leave it to chance, though. Who knows what I might get that I might never have tried? Their prices are cheap enough to pick up a 15ml of something I *know* I want to try.
(not all at once, mind you, but I pretty much do a weekly order of about $20)
