Hope I have done this right!
Cooks Safety Matches are running a promotion in Sainsburys. Buy x 2 47p box of matches - download voucher, take the voucher and the x 2 outer match box sleeve to one of the nominated salons and choose from 10 different mini beauty treaments. Treatments last between 15 and 30 minutes. Not bad for 94p. Salons are a tad sparse but some of you may find this useful.
