First decide on what appliances you want which may or may not be the same brand and may or may not be carried by Costco which has limited brands.

I am remodeling and bought all kitchen appliances as well as washer dryer.

Once I had decided exactly what appliances I wanted, I called several places in my city for their best pricing and created a spreadsheet which included any delivery charges and any installation costs.

In the end I wound up purchasing from Pacific Sales which is owned by Best Buy because they made me an offer I couldn't refuse. They matched all prices - gave me free installation on everything and free delivery.

I am on the fence about extended warranties as I think they are generally not a good deal. Far better to put the money in the bank and just pay for any repairs but I might wind up getting one or two selectively on those appliances which seem to be problematic - i.e. people seem to have more issues with refrigerators versus a Bosch dishwasher - my old Bosch dishwasher was installed in 2004 and never needed a repair.

Costco can have some good prices but their selection is limited. You can look at their website to see if they have what you want. I heard that it is possible to try to negotiate the appliance stores and you may have better luck with the locally owned stores vs. the big box. And if you are buying all of your appliances at once, that will give you the the best leverage. Personally, I’m not a fan of extended warranties. I’d rather buy a product that is made well. (So check Consumer Reports or other places that test the products.) FWIW, some friends bought KitchenAid when they remodeled 10+ years ago and had lot of problems and had to replace the fridge and dishwasher. So even spending more $ is no guarantee of good quality. FWIW, I think Kitchen Aid may be better today, but who knows?

Extended warranties -- lots of opinions on those and most say "no", but with the more complicated electronics in appliances these days, I've gone from a "no" to a "maybe". When I bought my 4 appliances last year when I renovated, I decided to go with an extended warranty (the first time I've done that in 30 years).

Where to buy - Costco has good prices and a great return policy (for any reason), but their selection is limited. I would recommend you decide on what you want, and if it's available at Costco then go ahead and buy it from there. I always buy my major appliances from a local chain from whom I get a reasonable price and good customer service. I could probably get the same appliances a few hundred dollars cheaper on line, but the peace of mind with dealing with a local store (with good service) is worth it to me......if I have a problem, their staff have been very helpful (even if it's just a problem with a delivery date or something).

I've had good luck with Best Buy (Pacific Sales) also. Great service. Do ask them to price match.

You might want to buy your appliances from an appliance store that also services them and does so in a timely manner.

Appliances come with warranties which are pretty much useless when you need repairs and can't get any repairman to show up. Most manufacturers don't employ their own repairmen but hire independent contractors, or at least they theoretically hire them. Problem is, there are not enough qualified repairmen who will work for the low pay that the manufacturers offer. So good luck with having your appliance repaired - never mind the warranty. I have friends who had non-functioning appliances for months and months on end, with the manufacturer declining to replace them since theoretically they could be repaired, but with months long wait time for service, what is the point? When a repairman finally would show up, they either weren't familiar enough with the particular brand to diagnose the problem correctly, or didn't have needed parts, and they would leave without fixing them. Another couple of months would pass with nobody showing up etc....a nightmare.

So we bought all our appliances at a local appliance super store (Abt), who employs a small army of repairmen themselves and we know we can get swift service if needed. (Be aware, Abt only service appliances purchased through them.)

Yes to extended warranties. At just over 2 years of age I had to replace the icemaker in my freezer, the electronic control board in my fridge, and every.single.part in my DW. They are all Miele appliances.

I bought a range, range hood, dishwasher, and refrigerator from Lowe's. I was able to defer the delivery, and called them back to schedule when my contractor was ready. The delivery guys were great, and everything went smoothly. I can't rate installation since my contractor did that.

I've heard stories about others who've had bad experiences with Lowe's, but the one in my area is one of the better ones I suppose.

I've never bought an extended warranty or service plan, and never will.

Abt

got all of our kitchen appliances from lowes, not only did they price match from the cheapest places in town but they beat the price by 10% I also was able to purchase every appliance I wanted free delivery and at the time they just happened to have a no tax promo.......some time it's worth checking around

FWIW, I have bought certain items from ABT but they were not the lowest price when I was purchasing all my appliances recently - even with the nonpayment of sales tax factored in which the Supreme Court recently ruled on.

Perhaps if one lives in Chicago and ABT is the local supplier, it's different.

When you are buying as many fairly expensive appliances as you are, you have tremendous bargaining power and will probably get a better overall deal from a local supplier.

I got pricing from a true local appliance store (one store) and two small local chains and one national chain (Pacific) and was able to negotiate a great deal with Pacific. As I posted, they price matched everything plus threw in free installation and delivery. Installation was theoretically not insignificant for me - wall oven; microwave drawer; hood vent; water line for refrigerator; washer and dryer; dishwasher.

If your employer has a discount buying program, the GE prices are very good.

@ahren - ABT is a Chicago based seller of everything - computers, appliances. They have a great on-line website. I've bought Apple stuff from them because I saved on sales tax and Apple products are not discounted.

I wouldn't buy a bunch of appliances from them since you can do better on price by negotiating with a local store - at least in my experience.

Be sure to ask about the return policy wherever you plan to do business. If you get a dog or are just not happy what are your options? Of course it's hard to beat Costco's 90-day no-questions-asked. I found limited options with BestBuy (15 days but unclear if you're just unhappy), HomeDepot - no returns at all, Sears also limited. And as mentioned if there's any support issues should you need help (this usually pertains to Samsung, LG).

Check your credit cards. Some of them offer extensions to manufacturer warranties. It usually extends just another 2 years past the manufacturer warranty. Good for a back up or other option if the manufacturer gives the run around. Amex has been reliable for me. Sometimes if it is not an easy fix they credit the card back.

Where to buy.. depends..

If price is the only deciding factor, then a big store with a great price match policy. The big stores often sub out for service calls, so it's a gamble.

If reliable service is wanted, usually a local smaller appliance store which has their own service team.

"usually a local smaller appliance store which has their own service team."

The store I bought from doesn't have their own service team but they do act as a go-between if there's an issue. When I had a problem, I called them, they called the appliance company, and the company called me back to set up a time. Not as good as their own service team, but does take away some of my hassle.
