Another month, new ATM vouchers. The ATM will charge you $1 for a balance enquiry and $2.50 for a withdrawal. However, you should have a debit card that gives you free ATM use via an instant rebate. This is available to ING Direct card holders (amongst others). Coles MasterCard holders can make a balance enquiry for free.
At the end of your transaction you get the option to choose from four vouchers. My pick this month is the free Coles Prepaid $2 SIM. The 30c coffee and $1.50 hot chocolate are still available. You can also get a voucher for a Twirl Mint 39g for $1.
Coles Prepaid uses the Optus 4G network. The SIM is triple fit, so at the very least you get a free adaptor. It doesn't come with any included credit. This deal was last available in January.
Are you sure this is there? I went on Tuesday night (March 1st) at about 10:30pm and none of the 4 vouchers were for freebies that I can recall. I recall seeing the $0.30 coffee, something half price in the upper right corner and the $1.50 hot chocolate. I forgot what the other one was, but it's probably the half price Twirl Mint thing you mentioned.
