In spite of my 4-year anniversary of being on OzBargain, I figured I should post a bargain today. Sorry it's nothing amazing!
Buy 1 Get 1 free Big M at Coles =)
NOTE: The details listed on the attached voucher indicate that you must surrender an original copy. Whilst I have tested this with a printout, keep in mind it can't be guaranteed.

Sorry just to clarify - do you buy one and they give you this voucher for another?
