Sold my 512 LCD to them on Wednesday for £319 cash, they’re now offering £183. Other models looked to have dropped down heavy too.
Average sold Ebay listing looks to be down from around £360-370 to £290-£300 as well.
Don’t sit on it too long if you bought an OLED with the intention of using your old model’s sale to subsidise the upgrade.
Or sit on it longer. It’s not like they’re going to become valueless. Soon after that they’ll be ‘original first models’
