I really do not fall for too many of these ploys as I go shopping with my own agenda - more of that on another occasion.
We saw a group of women who were tested to see how much influence the packaging of a product had on their shopping.
For the same cake - when better packaged - a number were prepared to pay up to 50% more for 50% less!
Wrest yourself out of this appalling habit and watch what that would do to your shopping bills over a year. For many this would represent savings into four figures annually if observed with all purchases.
