Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

Great TV

Jimmie2 12/6/2023

I bought my new TV a month ago on sale and am tremendously pleased with it. The clarity of the huge picture is truly remarkable. Watching a football game on the TV is truly better than being in the stands because you can see so much more detail.

First OLED tv gamechanger

Bobby_1511 11/25/2023

The LG OLED B3 TV is an absolute steal for what it offers. Im blown away by the stunning picture qualityrich colors and deep blacks bring movies and shows to life like never before. Its sleek design adds a touch of elegance to my space. The user interface is intuitive making streaming and navigating a joy. While the built-in speakers are good hooking it up to a soundbar truly amps up the experience. Considering its top-notch performance and the premium feel it brings this TV is hands down the best bang for your buck.

Connection issues

Paul Thibodeaux 10/6/2023

Purchased through Costco about 6 weeks ago. Immediate problems hooking up to ethernet. I have ATT fiber and ethernet cable was outputting strong signal but the TV was not recognizing the ethernet signal. After about a month of trouble shooting with LG Costco and local people the TV switched from Wi-Fi to ethernet. No one could explain why or what happened. I continue to monitor the connection but extreme headache as it should be plug and play.

Great resolution

Paul Thibodeaux 10/1/2023

Purchased a month ago thru Costco. Immediate problems that it wouldnt connect with ethernet. Great ethernet signal but TV didnt recognize signal. ISP and local tech came out and it began working but no one could explain why. Not sure if it will continue to work. Second the speed test on the TV extremely poor. Know the TV supports 100Mbps but only getting 15Mbps. LG customer service is very poor and stated TV getting 15 Mbps is good enough. My research shows 4K broadcast should be over 40 Mbps.
