eh. if you get it from an authorized dealer, they don't really care. I have a Thermador range and dishwasher, sharp microwave, subzero fridge/freezer columns, XO undercounter wine fridge, Zephyr hood. My dishwasher and fridge/freezer are custom paneled, so pull hardware style match. My dealer gave decent discounts and free delivery for the set. He didn't care if they matched. He just looked at the final dollar amount. Some of the upper tier appliance manufacturers entice you that way. Thermador for instance, if you get a range, get a free dishwasher. Add a fridge and you get a free range hood. Wolf/Subzero has something similar. Matching appliances are just aesthetically pleasing, and controls may be more consistent. At most price bands though, they're pretty equivalent in terms of feature set. Handle style will obviously match as well. More on reddit.com

I agree on the independent authorized appliance dealer. Watch this video, Ben gives good advice https://youtu.be/cRgbfxJ8MTQ More on reddit.com

If you're worried about quality being different because it's a Costco exclusive, just look up the model numbers and see if they're sold elsewhere. Some appliances are the same as the other big box stores while some are not. I haven't purchased from Costco but I also am shopping for our house we are building. Through Costco I have been able to pick and choose appliances from different brands and still get a great price (in theory, in my cart, I haven't actually purchased anything). I'm looking at the Costco exclusive LG washer/dryer (front load), Fridge TBD but also 3 door French door with or w/o ice in door, and 800 series Bosch dishwasher. It comes out to about $3,500... no range or microwave but we are getting washer/dryer which you did not list. The dishwasher also is quite the upgrade. If people start telling you the Costco specific appliances are worse quality then I could just as easily buy the other model for the same laundry machines, they'd just have different coloring. Given they're the same unit with different coloring I don't see why the manufacturers would skimp on material. It'd probably cost more having a different line up in manufacturing than to just make the machines the same. Before buying an LG package make sure to read this thread on the LG fridge compressors. I'm looking at either a whirlpool fridge or the LG max counter depth (with no ice in the door as the one with ice in the door might have the bad linear compressor) ETA: Costco's extended warranties are cheaper so that can play a part as well! HD gave me $270 for 5 year warranty for a $1,800 fridge and Costco can get the same warranty for me for $115. More on reddit.com
