Day late qp's usually contains enough numbers to make a winner..
I have taken others tickets that I was asked to discard because they were not winners.. and ran them for the next draw .. and collected..
I always ask if they want to keep the same numbers.. and always I hear "no".
Another thing I do .. If a person has several winners on several tickets.. I keep those and make combos with them. Seems that the numbers repeat and I will luck up with a winner.. Not a lot of money.. but a closer chance than with qp..
