Alternatives to "usual suspects" when buying kitchen appliances?

[Ilya Z.]

We're rehabbing a flip which includes a complete remodeling of the kitchen. So in a few weeks will need a full set of appliances: fridge, dishwasher, electric stove and fan. The spread on the house won't be very big, and the potential buyer is likely going to be a first-time home buyer, so we're looking for something basic (preferably stainless, though, based on the overall design). Are there alternatives to HDepot/Lowes in the DC/Baltimore/Frederick area where I could find new appliances for cheaper? Don't want to buy online (ebay/amazon/etc) and prefer to avoid used stuff, although might got for floor items/open-box/etc.

Thx!
