From a Google AI Search Result comparing the 83" B4 to C4.
LG B4 OLED (83-inch model):
Processor:
The 83-inch B4 uses the same α9 Gen7 processor as the C4, unlike the smaller B4 models.
144Hz Refresh Rate:
The 83-inch B4 also supports a 144Hz refresh rate, unlike the smaller B4 models.
Four HDMI 2.1 Ports:
The 83-inch B4 offers four full bandwidth HDMI 2.1 ports for 4K/120Hz gaming, unlike the B3.
Brightness:
While not as bright as the C4, the 83-inch B4 is still bright enough for most viewing environments.
Cost-Effective:
The B4 is generally more affordable than the C4.
In Summary:
For the 83-inch size, the C4 offers slightly better overall performance due to its brightness and processing capabilities. However, the 83-inch B4 is a strong contender, especially since it shares the same processor and 144Hz refresh rate with the C4, and offers a more cost-effective option. If you prioritize the absolute best picture quality and are in a bright room, the C4 is the better choice. If you want a great picture at a more budget-friendly price and don't need the absolute highest brightness, the 83-inch B4 is a great option.

It must be based on location. It's showing that I can add it to my cart.
What part of the US you are in?
I just tried again and now it's saying it's OOS for me. I snagged one before posting this deal and it was still showing as available when I tried again this morning around 8 AM.
EDIT: I just tried again at 8:53 PM ET and I see the "add to cart" option again.

I knew the 83 inch B4 would be first to sell out. It's internally a C4 with a slight brightness nerf, so it's the best value OLED available today for the price. The 83 B5 is just a regular B5, unlike the 83B4.
The deal you posted in May was full of great info. I almost hopped on it, but by the time I got around to it, the promo code didn't work anymore. Then the free wall mounting option died. Then it went out of stock for almost a week. I got my notification last night that it was back in stock, so I hopped on it quick with the new promo code.
