Got this in the mail
Get $20 for $100 spend for 4 weeks. Code send to be the same each week. I imagine it will work at the self checkout at Brunswick (Barkly Square doesn't have self-checkout).
It says for Brunswick Woolworths so not sure if it'll work else where, can always give it a try. Valid at Brunswick & Barkly Square stores only
Damn I'm in brunswick, I need to find this catalogue
