So I saw this in store today and I thought that it was a pretty good deal, which appears to be an online deal as well. There's tons of shades and there's also the 3 for 2 deal on the Perfect 10 range, which works out as 3 boxes of that for £14.
Works out as around £3.33 a box which is super for this brand, I think. A good hair dye too. This seems to be a deal across all hair dyes, if Nice 'N Easy isn't your preference. This is pretty good when you consider that Boots are currently selling these on offer for 2 for £10!
