Amcal chemist rewards card

Aussies, do you know Amcal chemists have a rewards card?

You can accrue points when you purchase non-prescription items at Amcal, then you can use the points as money to purchase things in-store. The points don't expire, they add up quickly and the staff are very helpful and knowledgeable about the scheme. A few times a year they have special offers, and in the mail you'll receive coupons that you can use on specific items that will get you extra points. One of the coupons is double points if you spend over $20 or over $50 in one transaction.

In general, I'm a bit leary about rewards programs, you often need to put in so much for very little return, but this one is worth it.
Ask about it at your closest Amcal.
