I almost always buy my electronics from Costco. They often tack on an extra year of warranty at no additional cost. They also make sure the vendor offers good support if the warranty is needed. My only complaint is their website sucks balls. The search is atrocious and it is hard to navigate. I would gladly give them more of the retail dollars I spend on Amazon but they make it so hard for me to do so.
Previously using their credit card also gave double the warranty. Citi ( I assume it was them and not Costco) cancelled this. Still, sometimes yes the warranty is better but not as stellar as it recently once was.
Also buying and returning appliances on Costco is worlds better than say HD or BB. Easy returns for 90 days, haul away, basic install all included.
Their website is pretty crap. But. You haven't seen anything until you use their mobile app.
It is definitely one of the worst thing I've seen. I mean Subaru's Starlink was way worse, but IDC it's a car and I don't need the crappy app to use it. Costco's I want to be able to use, but can't.
