Lowes (and probably home depot too) usually run black friday deals where if you buy 2+ appliances you get a couple hundred off with increasing amounts the more appliances you get. You don't have to match by brand. The extended warranties from Lowes are worth it too imo.

Be sure to include a 5 year (or longer if available) extended warranty in your shopping. Prices on these vary a lot and are cheapest when purchased with the appliance. Unlike the past when I thought all extended warranties were rip offs, I now feel this an essential part of a major appliance purchase.

6 years ago I paid about $230 for 5 year coverage on my stove and fridge (both included in that price) and I had about $800 of service calls on the fridge at about 18 months old. Also paid about $100 for policy on my dishwasher and had a repair that would have cost over $400 also in second year.
