(sorry, after posting it, I found that crazyterrier2000 has already posted this deal several hours ago)
I just got this from email news letters:
Free L'Occitane Olive Body Lotion worth £8.5
When you like us on Facebook today.
Basically when you visit it's facebook page, there's a tab called "FREE OLIVE...", and you can register your details there. Then you'll receive an email. You just print out that email and get the lotion from participating stores. I've got the email, but not sure whether I'll be bothered to go the a "participating store" because it's quite far from me. Anyway for those who live nearby the stores, it's a good deal.
