8-10 supermarket brand ones for a quid. think i'd argue they offer the best joy-to-pence ratio of any snack.
y'don't see the raspberry ripple ones about much nowadys, though. shame, they were a treat.
only slight bugbear is that they start to taste of their wrappers a bit if you don't eat them within a couple'o weeks.
three cheers for choc-ices.
