That is kind of dissapointing, At my local store I have had fairly good dealings.
I was "bartering" with the manager over an air compressor that- as it sat on the shelf as display, had a crack in the bottom of the crankcase. no oil had been put in it so it was "clean". I was confident I could fix it with "jb weld". I low balled it and he said to wait and he would check with the receiving manager to see what the "break even" price was. Ended up paying $50.00, not too much more than my offer.
Some times i don't undrstand why they put things on "clearance" at the price they do. Once, a row of walk behind mowers and a swisher trimmer marked at $50.00.....now I have a swisher walk behind.
To the OP: Maybe try to find out who the receiving manager is and work through them on one of the ugly sprayers?
