Tetris anyone?

We have purchased six large totes plus two large suitcases to fill with donations to take to Korea. Single grain rice cereal is SUCH a needed item, but I must admit, it is a bit bulky when trying to pack it. I've acquired enough boxes to try several different arrangements to see how many boxes I can possibly fit into one tote. This is proving to be more difficult than anticipated.

We have to fit THIS...

Into this...this is going to be TIGHT!!!

I'm hoping to have a tally of all the donations we've received and bought by the middle of next week. It may take that entire time to figure out how to get all this stuff tucked into our bags!!!
