I found this offer which doesn't say when it expires, but you get 10% off with WELCOME10 ,plus free shipping , a free gift bag, and a choice of a sample bag too with any purchase which includes travel sizes. Most people have paid £3.60 for an item (cheapest is £4) and had all the other items free.
what is Caudalie? A product or a brand? Since it already says the offer is available for UK only, I am not going to benefit from this 10 percent discount scheme. However, I can share this information to my friends in the UK.
