Here's a link to pre-register for the CPO, this option is not a monetary transaction so you will either have to still mail in, stop by Rapid Fire, or pay day of, but will get your name on the list. This list will take priority over players registering the day of too so please register early. This does not have a selection for $2 ace pot so let me know if you want that.

I don't see the link for the flyer anymore, sorry. We might have the website setup to take online payments soon too. Will post again if that happens.
