The more you spend the more points you collect.
For every dollar spent instore or online you collect 1 reward point. Once you receive 1000 points you get a voucher to redeem either instore or online.
Note, whilst the points don't expire the voucher is valid for a year. If you redem your voucher but do not use it within the year talk to one of our staff about adding the points back on your account.
You can always check your account balance either by clicking the link in the email, or choosing the "check rewards" button at the bottom right of the screen.
