I'l start with a few so that 'You Get My Drift.
And confession time also, I'm guilty of using many of these.... and often
It's not rocket science
At the end of the day
Bad hair day
As you do
Bling-bling
Cheers
What goes around comes around
Pushing the envelope
Do lunch
No pain, no gain
Talk to the hand
I can see where you're coming from
Moving the goal posts
Playing hard ball
You do the math
and finally,
Thinking outside the box
