hey to any of my Canadian friends could someone tell me where I could buy cake boxes that would fit a 2 tiered cake... bulk barn maybe?

Hiya,

I usually use 2 box bases (use one as the lid) and tape the top one on.

I also use the extra lids from doing this as risers. Cut the flaps off of 4 lids, tape them in to the corners of the base vertically and then use another base as a lid.

Hope this helps.
