bugbitten - you actually have an idea here - If everyone agrees, we could have ticket numbers 1 to 100 - and you will be assigned your number based on the check arriving.
Then we have a drawing after all 100 are here, and announce the winning number.
Each night, unless I am out of town on biz, I would post the checks received, and each person's number.
This way, $2500 comes in, and back out again.
I send Axiom a check for the EP-600, and it gets delivered.
