Check out BestBuy. They have price matching, so if you find it cheaper, they'll pay you the difference back. Unfortunately Costco is usually excluded, which is not a big deal anyway. Costco usually sells exclusive models the other retailers don't, so it's impossible to do a price match model-to-model anyway.
Costco has a really great return/warranty policy for electronics. They also get models that incorporate features from higher end models for less cost than the higher ones.
You should look at the pictures to be sure what you like. The 4K pixels for a screen size over 40" is a good feature. I have a Samsung 42" 4K that is outstanding. It also tunes in Over-the-Air digital channels easier than my older Sony's. The smart features are also very good, but I use an Amazon FireTV stick now, so the on-TV apps get little use here.
The sound quality in my Samsung is better than the Sony's I have, but I normally use those with my home theater speakers.
If everything on your old TV is still to your liking, you might consider a sound bar or other external sound system. You'll get better sound than before, and when you find a good deal on a TV upgrade, you can still connect the better sound system to it. External sound should be less expensive than a new TV depending on what you buy.
My best advice is to check the Black Friday ads coming soon. October is almost over.
I bought that TV on sale at BestBuy. Looks like the current online offering that's closest to mine is this one for $399 on sale:

Thanks. Yeah, I was looking at BestBuy too. Sams does (or did) have an offer for savings if you bought a Samsung TV with a soundbar, so just another point to compare.
My current TV is a Sony Bravia 46" and the picture is ok. However, I've seen some newer TVs at friends' houses that in my price range look way better. I mean 1080s is still great, but some of the newer stuff is noticiably better. I was planning on getting a sound bar anyway and actually recently disconnected all my old receiver and other components. Just life got in the way.
If its just your speaker that is broken then you can get a soundbar for as little as 60-100.
Two things to keep in mind; new 4k tvs upscale the picture of cable tv or dvds to look even better than they are. Even non 4k content will look better. Sound on new thin flat panels is awful, be warned. Thin, tiny, rear facing speakers cant be expected to do much.
If you replace the tv i highly recommend tcl.
Love the roku interface and simple remote.
55" 4k is regularly under 400 at costco, extended 5 year warranty included. I have a samsung mu8500 in the living room which is one of the higher end non oled tv's and i see little difference and its twice the price of a 65" tcl. At the time tcl just came out so i got the mu8500 because i didnt want to spend even more for the only tv's that were better, the sony x900 or lg oled.
I like the base model tcl so much i also tried their upgraded p series with voice control,120hz,and full array backlit led instead of edge lit. Its directly comparable in picture to my samsung. Those arent regularly carried at costco but best buy has them for 650 regular price and they go on sale for 50-100 off. Costco had them for 2 months last year but with no voice control. They stock different variations of tv's that best buy stocks so people cant price match. My samsung is called the mu850 instead of mu8500 as its known in all other retail stores.
Thank you for the feedback. As mentioned above, I was looking at getting a soundbar before the TV speakers blew. I am not into home theater stuff as much as I used to be, but would be nice to have more than the basic speakers of the TV.
Before this week, I had not heard about TCL, but in my research, they got very good ratings. They and Samsung seem pretty high up there in ratings and about the same price. 55" is what I've been looking at. I'm at 46" now, which is fine. I think 55" would be good for my living room. Since my living room isn't that wide, anything larger would be getting too big.
I haven't ruled out OLED, but I'm thinking not and mostly for the price. I'm thinking of staying in the $500-600 range. From what I've researched so far (not that much), that gets me in the range of Samsung NU7100 series (4k UHD with HDR) and TCL 4-6 Series ($380 - $450)..
