My son is a research-before-you-buy addict and he can tell you details of every set available if you are looking for something... what he found is there are different levels or grades of big screens and break down somewhat in the lowest levels having a 5000-6000 type model numbers, middle of the road are the 7000 type model numbers, and the higher grades start at the 8000 type model numbers- then you get into the super expensive sets like OLED and some of the newer super duper HD touch yourself quality picture sets with built in Alexa, Fire Stick, etc....
For the most part Costco covers the higher end models- a few 7000 series, a lot of 8000 series and lots of the best of the best . IMO this is why their prices seem a bit high but you get what you pay for and their additional in store warranty is hard to beat. If you are a member you can get on their email specials list and they will occasionally have killer deals on some of their sets. Their sound bars are usually priced very well also, IMO- for the quality you get.
But hey, half the fun is going into an electronics store and turning up all the TVs and sound bars as loud as you can and leaving the area though, right?
Oh yeah- get a good surge arrestor for your house and you won't have to replace so much electronics. As an electrician I saw some incredible electronics damage to peoples' home electronics, ranges, refrigerators, you name it due to lightning. These days everything has electronics installed and home insurance quite often doesn't cover damage to all of it...
