Black friday deals on PMAs, Inverters, etc?

I posted this in the Solar forum because it seems to get the most activity. I am currently looking to buy components for a water wheel and thought id look around for some holiday deals. Figured at least one or two companies out there would have sales going on but i cant seem to find any. Has anyone come across any Black Friday deals or what not?

I'll put my link for info of a part of what I've done in picoHidro

everything you find and ..y, especially brushless servomotors at low prices
