just popped into our local Tesco's in Bromley & they had several xmas dvd's for just £1.
Bought a bundle for stocking fillers for next xmas.
Not sure if this is store specific but worth a look in the dvd section. The ones I picked up had £1 yellow stickers on but there were the same titles without the stickers on but the ones I had all scanned at £1 so I assume the others would too.
titles I saw are
A CHRISTMAS CAROL ... with George C. Scott (sleeved cover)
FROSTY THE SNOWMAN... Animated but in a nice silver sleeved cover
NATIONAL LAMPOONS CHRISTMAS VACATION
SANTA CLAUS THE MOVIE
MIRACLE ON 34TH STREET
SCROOGE... Albert Finney
