To each his own and there will always be a sizeable amount of folks who will not shop anything of size online. Personally over the years I have bought 7 TV's online or on the phone, Breakdown was 2 Sammys, 2 LG's, one Sony and one Vizio. Maybe I've been lucky but never had an issue with any set, other that a warranty visit on the Samsung after 14 months or so(was a known issue with capacitors).
The ones I've got without issue
- 52" Samsung / Amazon 2013
- 65" Vizio / Amazon 2015
- 32" LG / Newegg 2015
- 75" Samsung JU7100 / Samsung Dec 2016
- 75" Sony 900F / CP May 2018 (box was damaged quite a bit, but TV was fine. driver helped unbox, put stand on and power up)
- 77" LG C8 / CP Aug 2019 (box was perfect so I didn't even unbox at delivery because I wanted help and to take time, was fine)
My experience and what I've heard is 65" and smaller is usually delivered by FedEx where larger sets come by way of real freight companies.
These large companies figure shipping as part of their overhead and usually try to make returns easy. Amazon will even send someone to get the TV if you lose the box for whatever reason. Both sets I bought this year were bought through Chris at Cleveland Plasma(great guy), but they were shipped direct from Beach Camera with full warranty.
I know of at least 5 friends who have purchased online within last 12 months. One got a TCL and returned it but the rest were all happy.
Mostly the only feedback you will read about is the very few that have a problem. There are bad panels and shipping damage does happen. Chris told me that total returns were well less than 5% and probably closer to 3% including shipping damage, defects and buyer remorse.
I bought a 55X900E open box at Best Buy right after xmas '17 and it was a great deal I stumbled upon, but most always you can save 20% or more with e-tailors. But hey, I'm a gambler and haven't bought extended warranty since I bought a plasma at Costco around 2006. Best of luck, if you keep eyes out you will find the deal you want...just be patient
