There is a 99p store right next to my chiropractor's office, so I pop in every other week. Today I scored a set of 6 silicone cups as well as a set of 10 mini cups. They had them in orange, pink and blue and only 99p per set!
Compared to what I have seen them priced at elsewhere, it seemed like a good deal so I thought I'd share for the UK members. :)
