I got caught out by stealth shrinkflation buying a 200g butter which I expected and thought was the usual 250g butter has always been.
Miffed when I got home and realised I'd got 20% less butter than I thought.
Shelf ticket price in Asda displayed price, pence per kg and weight as the 250g - misleading...
So the next week I told a member of staff the shelf ticket wasn't right for the product anymore and they said they'd change it.
Over a month later it is still on display and being advertised as the false cheaper price.
So I took matters into my own hands. I'm officially old.
