Hi damadhatter
Myself and my partner have just launched our new skin care & cosmetics web site The Soap Store UK
Before this I worked as a postman and had lots of problems problems with my skin especially on my face even though I was concious about not rubbing my eyes and things like that all shift.
I soon realised that diet is extremely important for a good skin condition. Foods rich in vitamins C, E and A are essential.
I too have a problem with oily skin and found that a light moisturiser that was quite watery helped me as my skin already had a lot of moisture in it.
We don't sell moisturisers though just handmade soap

I find superdrug quite cheap
Cheers
