For Goodness Shake Banana, strawberry and chocolate, on ASDA online as well.
Excellent value, found elsewhere for £1.49. 20p is a bargain.
They only had about 10 left bottles when I got there, 2 strawberry, 2 chocolate and 6 banana, the banana ones were 50% extra, meaning the bottle was 495g instead of 330g.
They are in the same section has yahoo and other milkshakes, not by the fridges though. Buy them whilst you can.....
