I got another stamp on my coffee shop loyalty card yesterday.
As I took it from my wallet, I momentarily brought out the wrong one and I compared the two cards.
One card had ten stamps to collect and the other had only nineï¿½
Until I looked carefully, because then I noticed a difference ï¿½ which makes a big difference to the psychology.
On the card with ten boxes, the first box was pre-stamped.ï¿½ So, when I got my first paid stamp, I already had 2 out of 10 ï¿½ or one fifth of the stamps.ï¿½ With the other, when I first got a stamp, I had one out of nine ï¿½ a far smaller proportion.
With both cards, one paid stamp leaves eight to get and two paid stamps leaves sevenï¿½ï¿½ But the second card is the more effective.
Advice for Coffee Shops ï¿½ How to make this more effective
It is tempting to say ï¿½have twelve boxed with three pre-stampedï¿½.ï¿½ The proportions are even better ï¿½ your fisrt paid stamp takes you to one third collected.ï¿½ But take this too far ï¿½ and youï¿½d need research to know how far is too far ï¿½ and people will see through the ruse, negating its value.
ï¿½ but this will work
Rather than have the first space pre-stamped, leave it blank, but instruct the baristas or waiting staff to ï¿½do you a favour when you get your first stamp: ï¿½Iï¿½ll tell you what ï¿½ Iï¿½ll give you an extra stamp because you smiled at meï¿½.ï¿½ Not only will this personal approach trump the pre-printed stamp, but it will probably earn your staff a bigger tip too!
