I called the store this morning to ask if they offered contractor discounts on Thermador, as another big reseller in town offers a 5% discount. BEST said there is only a discount if a Thermador refrigerator is part of the appliance package. When I told them that there was another reseller offering 5% contractor discount without that requirement, his tone completely changed. He said "well best of luck with them" and hung up on me. HUNG UP!
I was prepared to spend north of $15,000 on my appliances, but was never given an opportunity to share that information. They obviously didn't want my money, which is fine. I'll give it to the other reseller who treated me with respect and even reached out to my contractor to obtain his information and to fill out the proper paperwork.
Shop around, folks.
