Interesting site, looks like they use at least LorAnn's and PA, probably FA, and maybe FF or Bickford's (ignore all that if you're confused). However, they don't really have any complex mixtures and they have a LOT of flavors, so it makes me wonder how extensively they have tested their mixtures. I'd imagine they are hit and miss at the moment if they are new, but they could turn out to be good. What flavors are you interested in there?
