LG OLED TVs will hit a new low price for Black Friday. Now's the time to buy

• The only differences between the two are cosmetic (different stands) and audio-related (the B7A lacks Dolby Atmos decoding and has a different speaker configuration). During the sale period the 55-inch C7 will be $200 more, and the 65-incher $400 more, than the B7A. I don't think those differences are worth the extra money to most buyers.
• I don't think the price, especially on the 65-incher, will get any lower this year. In 2016 LG announced a similar sale and its pricing never got lower. In fact it increased in price a bit near the beginning of December, according to Amazon price tracker camelcamelcamel.com. That sale had a pretty tight two-week window.
