I don't like the buying books method at all. The ROI for the most part is always never going to matchup. You can get lucky but most books are designed as losers. It's just the luck of the draw. I run hot and cold. I may go 2-3 days and do no better than a Ticket and then all of the sudden, I win multiples.
I am currently in a cold streak. Probably operating at a 50% ROI for the past week. It's just the way it goes sometimes.
I am ready for a new $10 game to replace LFL. That one is just getting stale. It's been around too long. Plus with only 2 prizes left, the odds just seem so remote. Then again, they are always remote unless you are the one who gets the magical card. That's what makes the games fun in my opinion. You just never know.
The little lucky leprachaun Asian guy at my liquor store hasn't given me a good feel on a ticket in awhile. When he does, I buy and his hit ratio is suprisingly high. He speaks barely any English that is understandable but I know when he says "Buy this one over that one."
