If you're in the market for some new cosmetics this weekend (or anytime this month in fact) then head to Illamasqua. The distinctive beauty brand is offering a 25% discount on any product from the range.
All you need to do is bring in your (preferably dull, boring and uninspiring) old cosmetics from any brand and you can swap each of them for a shiny new Illamasqua product at the reduced price. It doesn't matter whether your beauties have been used, smashed or broken and there is no minimum or maximum amount of products you can swap. Now that's what we call an offer.
