John and Karen Ord with their National Lottery jackpot prizes. Via Chronicle
A British couple unknowingly bought duplicate tickets for the same UK National Lottery draw, and won $150,000 each.
John picked up his ticket at a newsagents close to their home, not knowing that his wife Karen had also bought one from the local post office on the same day.
While this is a great stroke of luck for these winners, buying double tickets on purpose is not practical. It wastes money, and wastes the opportunity to spread your number selection over a wide range.
You need this spread to increase your winning odds.
Moral of the story: Celebrate this win with them, but don't plan to follow this accidental plan yourself!
