OK - I hate this and am seeing it more and more on ozbargain.
Loose - means the opposite of tight. 'My belt was loose'
Lose - the opposite of find, the opposite of win, to come last etc etc. "You've got nothing to lose" "I don't want people to lose out on this deal"
Go ahead, flame the crap out of me. But at least start getting this right.
iCare!
