Try a different vendor, some might still be selling last year stock at the old prices, others might have updated to this years prices which will be considerably higher. A lot of the increase (but not all) is because lots of oil refineries were shut down, plastic for making the jugs is from processing crude oil. Additionally crude prices are way up too.
Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
