Ooh awesome thread.
We've been saving lots this year so far.  We have managed to cut $50 off the grocery bill per fortnight, mostly just by doing a meal plan. 
I switched my phone to prepay and that is saving $50 per month 
 
 
We have been switching off stuff at the walls and not using heaps of light at night.  Aprils power was $190 and Mays is $130 woo hoo.
Maybe we should set a up a clothes swap thread on here for used clothes and just pay postage ?
I love searching through the second hand shops I've found really good stuff for $1. 
I'm making the kids trackies form now on and may attempt tops at some point.
