Have you tried going out of your area for appliances? One place I've been dealing with about 16-17 years, is an hour away. Another place is a half hour drive. Anything local to South Bend is sewed up.
I still check C/L, get a few that way, still check the alleys on occasions, run ads in C/L. You also might make a deal with the competition. The place an hour away is a dealer who sells trade ins, but keeps only the best. They don't sell anything GE, so I get all that. I get the refrigerators covered in decals, or the B/D Whirlpools, or some of the other oddball stuff, like Amana they won't mess with.
Trade in's are still out there, sometimes you have to be creative.
