OK, bear with me. There's a £5 voucher for Facial Skincare given with every £5 spend (as well as the No7 one), and this includes an abundance of Time Delay products which are less than £5 and will therefore be free.
Now, in the free Boots Health and Beauty magazine, there's a 200 extra points voucher with any Time Delay product. Get a magazine when you spend £5, then use the voucher to get a free Time Delay product with which you can claim an easy 200 points.
Sounds complicated but it's not too bad really :)
