Nails inc's sale is now live, and spotted the perfect 10 for £19.50. Think they had this price a while ago but different set of colours.
RRP: £140, down to £19.50! (RRP seems like a bit of an exaggeration but £19.50 is definitely pretty good for 10 full sized nail polishes! :p)
Free delivery over £40!
Hope this helps someone and Merry Christmas!!
