Not sure if this is Australia wide (our store is moving up the road so they may be liquidating stock not moving) but if it is...
The 5 pack of Irwin Marples is going for $10. I know they are not "good marples" but if you are new to the game, like me, a 5 pack of chisels for $10 is not to be sneezed at.
I grabbed a pack as they are normally $40 and $2 a chisel is just too good a deal to walk past for me.
