My own favourites are a head for points and shopper points. Both are UK oriented and clearly full time jobs for their creators. I have to exercise a certain discipline with them so that loyalty points do not become a full time job for me as well.
The first photograph is from Jermyn street in London, a place of no loyalty points but a unique atmosphere. The second is from the Bullring in Birmingham within which almost every shop offers points.I have set up a RSS feed from a head for points and shopper points so you may read if from here.
