Loyalty is for human beings, nations and transforming ideals.
The Temple in the City.
Brand loyalty is fostered by business through a process known as 'loyalty management'. The customer is the one being managed. Despite this it is possible to turn the process around and manage them right back. I hope you do so.

I have joined Quidco (as should everyone).
I have a plethora of other loyalty schemes but none of them amount to a hill of beans. Treat yours as a minor hobby. Few of them truly save money.
