I believe you can use up to 4 ticketless funds for a purchase. If you have more than that.....just make two separate ressies and then you can use 4 for each. One thing to keep in mind, however, once you use the TTF's....if you need to cancel the ressie you used them for all TTF's take on the date of the one closest to expiration. I never realized this until recently when I needed to cancel a ressie.
