As the online deal has expired I made a speacial trip to our Asda to see if they have the Vanish deal was instore, and IT IS. They had loads of them, both the PINK and WHITE boxes.

I've taken a photo to prove this is in store and very much available. Thanks.
£1.50 is a bargain!! I guess they won't last long
