Saw this deal initially in another thread on here, and was able to snag an Open Box 77" C9 for $2249 with $200 Best Buy Gift card. I asked about the $229 Bluetooth Speaker it was also showing you would receive online for the 77" C9(New), but the associate who helped me didn't see anything in his system. I didn't have a real use for it so I didn't push the issue.
Feeling very lucky as my store had just taken back a customer return on the 77" C9 that I ended up purchasing. It came with everything excluding the remote, which isn't a big deal as that shows up from Amazon for $31 in two days, but was very nice to get the stand and box to transport it home. Best part of all is the TV only had 48 hours on it. Display is perfect as you'd expect for those hours, with no dead or stuck pixels, and great uniformity. The remote missing, and a very small mark on one side of the bezel is the only downside versus brand new, which I can more than live with for the savings.
I called around to every store within 50 miles of San Diego showing Open Box stock, and it seems like this deal is meant to only apply to retired Display Models, which is still a screaming deal at $2049 effectively. Not sure quite how the one I ended up purchasing qualified, may be at a managers discretion. Definitely worth calling your local store if they show open box stock of what you want, bear in mind it rings up differently than the price displayed online so you must call.
There was still a display model up for grabs as well at my local store, and two other stores in San Diego, but they came with no box, stand, or remote. They will also presumably have in the 5000 hours of use range, however with how LG has been taking care of burn in and other issues, it likely wouldn't be a problem to have the display replaced by them if needed. May just be a non issue entirely given the 2019 models are supposed to be even more resistant to burn in.
Feeling very good about my purchase, as I had been causally looking to upgrade to a 77" C9 from my 65" B7, but wasn't all that interested over the $3000 mark.
