175 for a TH8320? Your distributors are a lot higher then mine for it.
I even called Powerline, the local Honeywell store. They were a little cheaper (around $155) but not much. The two distributors I called were standard HVAC suppliers, mostly equipment and ductwork. Perhaps if I called around I could find it cheaper.
My point being, however, that while I could certainly source this online somewhere, in MY area the going rate for that stat from an HVAC outlet is around $175. Comparing local prices to internet prices is never a realistic comparison, and calling out a company as a cheat because you can find it cheaper online isn't a valid complaint.
