You buy appliances for how you cook , clean and refidgerate not becuase they all match or you got a good deal That is why stainless has lasted so long for a finish , all makers have stainless and they all go together. Costco has decent prices but not always the best deal if you are looking for the appliance that fits your needs go to a good appliance store.

Choose your appliances based on function, features, and ergonomics -- with appearance thrown in as a final, more minor, thought. I think it would be unlikely that you would find everything you want all from the same manufacturer, and the financial benefit usually isn't that much anyway because often you'd end up paying for features you don't want. Have fun!

You may want to consider buying a used working fridge off craigslist for 100 or so dollars. Nothing like a rushed major appliance desicion to cause you future regret =(.

One of the big benefits of costco is they essentially have a forever return policy, that doesn't apply to major appliances though.

You can often save a little with a suite of appliances (10 percent ballpark would be typical). May or may not be worth it.

Costco has a 2 year appliance warranty (as opposed to 1). They also work with Square trade directly to offer an additional 3 year warranty for a reasonal amount.
