How many was the most lottery tickets you bought for one draw?

I once bought 20 $10.00 scratch tickets. I never do things like that, but I had this weird feeling. They were special Christmas tickets, and almost all the tickets I bought hit. I gave half of them to a friend as a gift, and one of his tickets hit for $40. He won $75 total, and I won all my money back on the tickets I kept, so I broke even AND was able to give a nice gift.
