Should I buy the LG C4 OLED before it sells out?

Yes—buy the LG C4 OLED before it sells out if you’ve found it at a strong closeout price, in the size you want, from a retailer with a good return policy. It’s still a very strong OLED TV: excellent picture quality, strong gaming features, 4K at up to 144Hz, and sharp motion.

I would not rush if the price is only modestly discounted or your preferred size is already gone. OLED closeout pressure can make shoppers overpay for the wrong size or a weaker return/warranty setup. The smart move is: decide your target size, compare the final checkout price, confirm it is new and returnable, then buy if it is meaningfully cheaper than newer alternatives.
