The bonus dibs are granted as soon as someone picks your items. They will be fractional like acorns. So if someone takes an item from you on day one, you'll get half a ticket and now you have 3.5 tickets. So you can only claim 3 items. But when someone else claims an item from you, you'll get another half a ticket and now you have 4.0 tickets to use.
Someone claiming your item on day 2 gives you .34 tickets. Day 3 gives you something like .2 tickets.
If you pick something and change your mind, you can cancel it. But I'll need to find a safe way to either revoke the bonus that was previously granted to the seller of that item, or something.... Otherwise people could add then delete all day long and give someone else hundreds of tickets which would obviously be unfair.
