Superdrug have a new promotion that when you buy any pack of Gillette Fusion Blades (priced at £7.99+ ) you can also take a Gillette Skincare Product free.
There are a few free products to choose from including
Gillette Series Moisturizer - normally £5.99
Shave Scrub - Normally £5
Facial Wash - Normally around £5.50.
Lots of other products that i don't recall.
These products are all pretty good quality so worth making the trip if you need some new blades.
