I did the Eddm last year and it was driving me nuts because you have to split the cards into bundles of 50 and rubber band them with a different ticket.
Even with the Eddm and got print a little over 500 you're still looking around 2000 and you have to handle them all. You can't drop them all at once either. They have a limit of maybe 5000 for eddm. I think I would pay 2400 all day to never have to touch them or design them.
