I usually buy this at £1.32 as I think it's a good price at that, however Morrisons now selling this at half price at just 66p.
Applies to both the dermo-active (blue) and dermo-invisible (orange) varieties.
This was in-store in Port Talbot and an 'end of ailse' deal if you know what I mean.
Have used this brand for ages. Good stuff!
