Tim Tam Varieties $1.82 + Delivery (Free with Prime) @ Amazon AU
The favourite for the lazy OzBargainer, Amazon is now matching Coles' half-price Tim Tams.
Bear in mind there is a minimum quantity of 3 required to order. (EDIT: There is no min. quantity for the Dark Tim Tam's… Think of the tress before you have 1 delivered to you.)
Don't forget to use your preferred cashback provider to save a few more cents in true OzB fashion. Or perhaps use the $30 voucher we all got from the WD 10TB Drive ordeal…
Dark Chocolate (Might be just me but I don't often see Amazon do the dark for half-price…)(Also no min. order for only the Dark variant.)
Edit: it appears dark is no longer available.
