All of the various ways to win a specific prize amount are combined into that prize level.

Thanks much for the info. I had won $15 on the first one, took it to another store won $20. Went back a week later and they were all gone !!
I'll keep looking, as this ticket is on the "2nd Chance list " for $100K

I'm guessing you live in Lancaster,,,So do I...Try AM-PM on Lynwood Dr.,they might have some,but with the top prize gone they'll soon be closing them out.,,I'll be looking,, if I see any I'll let you know...
                          Good Luck,,,,SCMOM

Thanks for the tip SCMOM, I'll check it out.
I wonder what they do with all the "leftover" tickets ?!
They ought to have a half-off-sale!
