Firstly, ensure you are registered for SPAR Rewards (see How do I register for SPAR Rewards above). Note that this is a once off process.
Once registered, all you need is your cellphone number or an active SPAR Rewards card (see below for more information on the SPAR Rewards card). Before paying at a SPAR till, inform the cashier that you are a SPAR Rewards customer. You will be asked to type in your cellphone number on to the keypad or swipe your SPAR Rewards Card. If you have any items in your basket that match SPAR Rewards available to you, you will receive your instant discount.
