Appliances - Where to buy

[Justin Wilkey]

Does anyone have suggestions on where to buy appliances that cater more to landlords? I have 16 units and I figure I'm going to be buying a refrigerator 1X/year at a minimum. I've been dealing with the big box stores (Menards, Lowes, Home Depot*, Recker and Boerger) and literally every one of them has been a big pain at times to the point where I'm willing to pay more to get reasonable customer service. Since many stores are just brokers for suppliers I'm hoping I can find someone that would like the steady business and be willing to help more when there are problems.

TIA for any input.

*HD has actually been the best. The other 3 were downright awful. HD at least had some semblance of customer service but they've even slipped as of late.
