Great GWP at Origins online (no voucher code req)

If you go to www.origins.co.uk and spend at least £25 you can choose a set of skincare samples at checkout, worth up to £15. There's a choice of 3; Core products, Mega Mushroom and Organics range. These samples, from my own experience, tend to generously sized so can last well over a week. There is no code, just choose at checkout from the 3 options they give you.

I have used these "sample sizes" in the past before and as the OP says, they are HUGE...some of them would be a good month's worth. Origins stuff tend to be lovely too!
