LG C4 OLED vs C3 OLED: Upgrade or skip?

"At $1,699, a 65-inch LG C4 OLED definitely feels a bit much, especially when you factor in the fact that you can get a C3 for $1,000 less."

Excuse me? On what planet is a C3 65" going for $699?
 
Yeah. I was not sure what date the article was written. I wonder if the price is fetched in automatically. The 65 C4 is $1499 at Costco (and other warehouse clubs with extended warranty) and the C3 I think is $1299. So $200 difference. I am debating between the C3 and B4 which is about $100 difference
