Since it is Teachers or Administrators that usually purchase using their own names, email addresses and payment details, it is the name of the purchaser we need to make a successful search. Establishing this is not always easy, as people change jobs, change married names, email addresses etc.
We need to establish a purchase has been made, by whom and which product.
Unless we can establish a purchase has been made, the only solution is to purchase again.
Have I, my school, or organisation previously purchased Sassoon fonts?
