Yes, Heinz uses the TEC III also.
I honestly doubt there would be any significant discount with a group buy. The Seame.com orders the dosers from the manufacturer (with the 110 v). Plus, they would probably have to be ordered all on one card (waiting for everyone, then collecting $$) and shipped to one address here in US, then they would need to be repackaged and shipped to the individual people.... bleh~
But I'll shoot them an email and ask.
