a hot patato

a penny for your thoughts

actions speak louder than words

add insult to injury

an arm and a leg

at the drop of a hat

back to the drawing board

ball is on your court

barking up the wrong tree

be glad to see the back of

beat around the bush

best of both worlds

best thing since sliced bread

bite of more you can chew

blessing in disguise

steal someones thunder

take with a grain of salt

taste of your own medicine

to hear something stright from the horses mouth

whole nine yards

wouldn't be caught dead

your guess is as good as mine
