For every $10 you spend at Darrell Lea, you get a free chocolate bar. Spend $20, get two chocolate bars, spend $30 get three and so on. For each $10 spend, you need a voucher, so if you're spending $30 you need 3 vouchers to redeem 3 chocolates. Valid till 31 July.
not bad at all, initially I was like big woop, a free bar, but then I read it properly lol
