People yawn at good service, delivering on time, and doing what you said you would – you are supposed to do that, right?
What they will notice, remember and talk about is getting the unexpected – that something different, and something extra. If you provide a repeat business like a restaurant or dry cleaners, you can deliver it at the end of the transaction, to stimulate another one. But if you provide something they won’t likely buy again, you should deliver it before they make a buying decision so it can influence their decision making.
What can you deliver to your customers that is unexpected?
Your strategy is always intentionally choosen. You are responsible for your actions and choices.
