We may have ten loyalty schemes running simultaneously and yet profit from them not at all. A thousand points in ten schemes is less useful than ten thousand in one.
This is not an absolute rule. We can keep a number of schemes on the back burner but not actively pursue them much. If the points fall into our lap, all well and good but we should not care very much about the matter.
Loyalty schemes may not involve points at all. One of my favorites is a supermarket that allows me to buy a sandwich for £1.20 and have a coffee as a free perk. Every purchase, no matter how small gets the same perk. One man bought an individual mushroom for a penny but I think I would be embarrassed to do this.
The supermarket (Waitrose) is expensive but not overpriced when all things are considered. I will use it as my top up location and will buy cakes, newspapers and emergency items. There is always something it is possible to buy if one must.
Be brutal with those schemes that clutter our lives and back only the winners!
A- I have three primary schemes, but only one favorite at any one time.
