TV from costco?

Does anybody have good / bad experiences with getting a TV from Costco? Is it better to buy it from the store or online? The return policy on TVs is 90 days so that is a big downside. How is their warranty in case there is a manufacturing defaut in it?

Edit: I am mainly asking if you ever received your TV broken and then had to find a way to deliver it back to the warehouse for a refund. I do not have a car. I've heard many horror stories of ordering TVs from Amazon and want to avoid all the hassle
