I'd buy the 3 if I really liked the quilt, but at least one regardless. At a recent fundraiser I REALLY wanted that quilt, and spent $30 for 9 or 10 tickets.
Didn't win, but oh well, it was for a good cause. I gave the losing tickets to my sister for Christmas, as the quilt would have been for her. :mrgreen:
(No, that's not all I gave her!)
The downside of charging less is having so many tickets, as well as the people who might buy a single ticket or group of tickets regardless of price only putting in a dollar or two.
A middle ground could be $3 for 1, $5 for 3, $10 for 10 and $40 for your height in tickets! A local square dance group does that and sells quite a few lengths; yes, they allow a tall friend or bystander to stand in for the buyer for measurement.
