Just been into 2 Sainsburys and seen the following:
Minimum 75% off all Halloween stock but mainly the costumes and fancy dress.
They have :
Glow in the dark ghost
Witches ,Warewolves , Skeleton pirates ,spiders , pumpkins , Frankenstein and more - ALL AGES AND ALL SIZES.
A better deal than the M&S that went up recently
You can also get loads of decorations , stickers , Halloween toys , teeth , gloves , stationary all 75% off.
And my favourite the electric creepy / crawly hands that make me laugh so much now just £1.49
IT IS NATIONWIDE - WILL GO VERY QUICK TODAY
