hi ya...cant speak for cornwall, but £15 does sound steep for a polish...i live in the north and charge £8.50 which i must say is the 2nd dearest in town, they start here from £5.50, highest at the mo is £10...my manicures range from £13 for a scentsations manicure and £16.50 for a solardrench manicure and £16.50 for a spamanicure, u can go to deluxe which includes paraffin wax and hot mitts for an extra fiver...vicx
