donna, your question is my question. I've never had the opportunity to test it, because the two big things I won were exactly what I wanted. The one for the TV was a First Place and I didn't want that sweep's Grand Prize AT ALL, so I guess Fate knew. But suppose I did win the GP and I wanted the FP, I've always wondered if I could ask them to Please downgrade me to FP and give the GP to the person who would otherwise be the FP winner.
Then, should they say No, my wondering about it extends to thinking maybe I could locate the lesser winner if they post the names of their winners, and offer the switch directly to the other person, who probably would want it very much. The things that run through your mind when you're sweeping, huh?
I hope I haven't hijacked the thread. I should say that, as many of us do, if there is a prize that I want, I enter the sweeps, even if I don't want the GP. I have the least expectation of hitting the GP, after all.
Accidentally winning a GP I don't want has never happened to me, so entering and daydreaming about the lesser prizes I would love to win seems like a reasonable way to have fun.
