I found this in the Superdrug in South Harrow. There is a clearance section next to the window. Couldn't find this offer online, or this product, yet the others in this range are priced at £6.45. Too good an offer to not share at £1.30! Might be worth checking in other stores. :)
Edit. I have actually just used this for the first time after a good exfoliation & my skin feels amazing. Might go back & get some more!
