These popular Sony (seconds) headphones are back in stock at the Sony store today. They'd sell fast even without discount code.
Many eBay Plus members would pay less with the monthly 5% discount code, September being the last month for this promotion. Expired.
There are also a bunch of seconds full-array local dimming 4K TVs and some OLEDs back in stock, but quantities are too low for me to post. They'd normally go quick too.
