"I used to play Big Wednesday, but the returns weren't very good so the lady in the shop said I should try this new one, Bullseye.
I picked some numbers and have played them every week since.

"When she handed over her ticket at Images Transformed in Napier the terminal locked with the first prize, and in all the excitement they forgot to check her other ticket.

The Napier woman and her husband planned to take an overseas trip to America, England and Hawaii with the winnings, and were still purchasing their Bullseye tickets.
