Breville Blend Active Blender 2 bottles set for £19 @ Morrisons instore (not sure if it's online). It's a better deal than Tesco's single bottle deal which is only 2 or 3 quid cheaper, given that the extra bottles are more than £5 (possibly £10?) each.
OFFER ENDS 1st of MARCH!
To avoid disappointment PLEASE REMEMBER TO SCAN AT A SELF CHECKOUT if the price on the shelf is still showing £29. There's every chance the label has not been updated to reflect this promotion.
