Six chocolate covered biscuits was probably too much anyway. Having a yellow Snack bar with a cup of tea was an exercise that almost always ended with no tea and at least one biscuit left - this is never a good outcome.
So the last time I bought a yellow Snack bar, I didn't really mind that the six biscuit squares had morphed into four and they were no longer square, but rectangular - I’m ok with this too, confectionery shapes are not a big issue in my house.
For some people though, 'shrinkflation' is a massive issue, viewed as a sneaky, corporate trick to force us to pay the same price for less product.
Think about Yorkie bars, Minstrels, Maltesers - all of them have mysteriously shrunk in recent years, while the manufacturers demand the same money they were getting for the larger product.
I’m happy to go with the rationalisation that a smaller chocolate treat means slightly less guilt around guzzling the chocolate in the first place.
But there is a line here that tests even the most compliant consumer - the shrinkflation of Christmas boxes of chocolates.
It started a couple of weeks ago in supermarkets - the towers of Roses, Quality Street and Celebrations, stacked high for Christmas, stomach-churning to see in September for a start, but also, the boxes are smaller than they were last year and the year before.
It took me a while to notice all of this. A few years ago, I marveled at how cheap the Christmas chocolates were in comparison to the expensive luxury they seemed when we were children. Now it’s pretty obvious why they might be under a tenner - you are getting a lot less in that smaller box.
Glenn Caton, who works for the company that owns Cadburys, explained this trend by saying: "If there are strong changes in exchange rates and input costs, you have to say 'how do we offset those as a business', and occasionally we do have to do that through pricing and re-sizing."
The tentacles of shrinkflation stretch beyond sugar-laden treats - now the makers of toilet rolls, pet food and even bread have cottoned on to the trick - get the shopper to like your product, then shrink it and charge them the same.
We’ll have more eye-opening examples and tips to avoid overpaying at the supermarket on Monday night’s Claire Byrne Live.
