Single post in Questions About Site Rules 2.0

I have a question about the "do not offer goods you do not currently have for a trade" rule. I would like to offer a raffle of sorts, but the conditions are a bit unusual. They would involve people pooling egg supplier passes (I would give them back as soon as the order is finished) and me giving away any extra specials I would be hatching during the day. Since there could be no winners, the rule could be enforced for this, but also since there's no payment, it isn't really a trade properly speaking, so I'm torn on if the rule applies to this case.
