Do you see loads of giffgaff ads hanging around when you're browsing the web? I see many giffgaff ads on pages giffgaff related (not refferal banners but ads!) Couldn't giffgaff save a lot of money by keeping the ads for people who are not on giffgaff? Ad spaces cost money - it is a waste of money to advertise to people who are already customers! I hope the marketing staff will save a bit of dosh by not showing ads to members - and hopefully with the money saved they can return it to their members!
