They sell them in packs of five in Tesco. But fuck that shit, I buy a box of 48 from the cash and carry.
Cat, you can still get Curly Wurlys. I believe they tend to be sold in the supermarket as they're classed as "retro" sweets along with wagon wheels and penguins.
They're a lot smaller too from when we were kids. There are a couple of places here where I can buy them
To be fair, when you are kids most things look big in your hands........
It took me a while to find it. but this is the size of a Curly Wurly when I was a kid. it was when I was a kid. Note the net weight on the pack 1oz (or 28.3495g) compared to what you get today which is 26g. Obviously the photos are not to scale, but just the weights are different.
