Absolute steal for a timeless look. Free delivery if you are a first-time customer and add 'Free Shipping with First' to your checkout. 14-Day Kogan First Free Trial Available. Most models still have a decent selection of sizes, but I'm not expecting this to last.
Other models are also on sale (all of below are made from canvas unless otherwise specified):
All Stars Hi Top
White - $50 (to clarify: the 'White' All Stars are leather. The 'Optical White' All Stars in the main link are canvas)
Mono White - $50
Navy - $50
All Stars Ox Lo Top
Black - $50
Optical White - $50
Navy - $50
Chuck 70s Hi Top (typically $10 more than All Stars)
Optical White - $50
Will keep an eye out for updates. Search "Converse Chuck Taylor" in Kogan if you'd prefer to update yourself. First post on OzB so forgive any poor formatting or mistakes :S
Anyone after low tops might want to check sense, some of the more unique colour ways are around $40. Some high tops on special too but they're a bit more expensive.
