Total

To come off with flying colours

To come off with a whole skin

To come off cheap

To come away none the wiser

To cast prudence to the winds

To cast pearls before swine

To carry coals to Newcastle

To call off the dogs

To call a spade a spade

To buy a pig in a poke

To build a fire under oneself

To bring grist to somebody's mill

To beat the air

To beat about the bush

To be wise behind the hand

To be up to the ears in love

To be in one's birthday suit

To be head over ears in debt

To be born with a silver spoon in one's mouth

To angle with a silver hook

To add fuel (oil) to the fire (flames)

Time works wonders

Time is the great healer

Time is money

Time cures all things
