In order to better understand your shopping experiences, we want to capture as many shopping trips/orders as possible. To make this easier, we will ask you to create a unique code, which will include the first three letters of your surname and the first three numbers of your date of birth. For example, if your name is John Smith and your birthday is 23/04/1975, your unique identifier would be SMI230. The most important thing is that you put the same code in every time so we can track shopping experiences.
