Sign up to Amart All Sports loyalty program and score yourself a $20 voucher to be used online or in store. You can pick up a card from the stores, or get one sent to you via mail.
Only asks you questions about what sports you enjoy, and teams you follow, then the voucher is confirmed via email. You also get a 10% discount to use as well.
I noticed the terms and conditions say discounts are only available on full priced products. Has anyone successfully used the vouchers on sale products?
