should I leave a box for the top tier when I set up? seeing that this is to be saved till the first anniversary?? I've only done two other weddings and I didn't leave anything with them.. should I have??

yes.

short and sweet!! ok.....thank you!

Ok, sorry to revisit this.. where do you find a box that size? I don't have enough time to order online! and I checked Micheals and the smallest that they had was a 10"

Well the 10" is better than none. A lot of coordinators, ok all of them probably like to have a coupla cake boxes to take care of any leftovers too. Just a thought.

And cake decorating stores have them in the odder sizes.

I'd probably just leave them the 10" and tell them to make sure they wrap in plastic wrap and foil before freezing even if they use the box.
