Went into my local boots in Mansfield today looking for a hair lightener. Happened to notice this was reduced to £2.04 on the ticket price, but took it to the till and it scanned at £1.02!
There were a few others hair dyes and products reduced too, I also got a nice'n easy for £1.50.
The lady at the till said they are probably not selling them anymore so are selling to clear. If you are going to boots anyway it's worry having a look.
