Went to an auction two weeks ago with the goal of getting another 500 gal fuel tank. They had 3 available, but so many people showed up with same idea they ended up going for over $900 each. Maybe the fear of higher fuel prices played a big part in buyers minds..Idk. The one I bought last year I got for $250. I did end up with a 150 gal propane tank on a trailer w/hose and wand for $360, so day wasn't a total loss.
