I only seem to have 'The Pound Shop'.
They have sold Dove Swirls and Hershey Mint Kit Kats (Hershey own the Nestle bit in America)
The cheap shop around the corner from where I live in the UK has a gorgeous bar, 'Carre Fore' or something, I think the choc is called.
It's with hazelnuts, so not one for the anti-nut league, but really good chocolate! And very cheap.
