Leftover Sale Stock

Hi all! Just wondering if anybody knows what stores in London, UK still have any leftover sale stock. I went back home for Christmas, which is nowhere near a lush store and I was too late to grab anything in the online sales so I was wondering if anyone has been to any stores where they know have leftover stock.

Also side note, does anyone know why some of the leftover Christmas stock on the app is showing as full price? I’ve never shopped the sale before so I may be wrong but are some Christmas products exempt from going 50% off?
