I got the following quotes without soundbar and extended warranty
55B6- 1.85
65B6- 3.10
Do you think this is the good deal considering the model is old and dealers are trying to clear their inventory
The extended warranty for 3 years is quoted at 40k
Amazon US price for B6 55" is
$2k (1.3L), and for 65" is
$3k (2L).
US prices are usually significantly lower than most other places. My two paise - if you are getting a TV that costs 1.3L in the US (that too, Amazon not a brick and mortar store) at 1.7-1.8L in India, that is quite a good deal - about 30% markup. The 65" however seems to be a 50% markup from the US Amazon price (3L vs 2L).
From whatever I am seeing, it looks like LG has been able to reduce the manufacturing cost of the 55" model - and its price has been steadily declining. The 65" however continues to command a significantly higher premium - possibly because the 65" OLED panel is significantly harder to make (especially error free). However, this is just conjecture based on price trends of OLED panels over the last year or so, and also based on some technical articles (side note: I have been looking into Universal Display, which is the company that supplies the dyes that make up OLED panels - their stock ticker in the US is actually OLED).
Short answer: 55" OLED, especially the B6 model seems to be in the sweet spot in terms of value for money and price

erformance. In fact, its price is actually competitive with other top of the line non-OLED 55" panels.
65" OLED panels still command a significant premium however, and it looks like the markup gets further amplified when you consider the India markup. Having said that, 65" OLED panel price has also come down quite significantly from the astronomically high territory down to "affordable premium" territory. Just that it has not come down as much as the 55" panel price, relatively speaking.
