Hi alta-babe,
I never said I specifically get $1000 every week. If I did then that was a mistake and I apologize. But I consistently do get large winners on a regular basis. For the $1000 and larger, I've noticed they usually come in waves. There will be periods where I get a lot of them then things will dry up, kind of like what we're going through now.
And the winners are usually scattered across many different games. But they're mostly concentrated on our most popular games. Mega Crossword, Bonus Crossword, mostly $5, $10, and $20 games.
As for staying away from retailers where they've had large winners. It would totally depend on how busy they are and how fast they go through their rolls. My most popular games I keep 2 rolls in each bin (saves me time in reloading) and with almost 90 bins going at one time, you can see how fast we go through our games. Also, we'll accept delivery of 40-50 packs of each of the popular games at one time and about 1/3 of each of those packs will be from different sequence of serial numbers. So that further randomizes which games goes where.
But to answer your question, if you're buying it from a store that doesn't move many tickets, then it makes more sense if you find another store under the assumption that multiple winners aren't in the same pack. But for a store that moves high volumes of tickets, then I'm sure they have multiple rolls for you to choose from and if you return the next day, it'll most likely be a different roll in the same bin. Hope all of that makes sense.
Good luck.
