Great Idea on securing RubberMaid Tubs

We are continuing to pack, pack, pack, and alot of things have been put into large Rubbermaid tubs with lids. Then our problem became how to secure them enough for shipping. (didn't trust tape in all the humidity). The Fed Ex woman gave us a great idea we wanted to pass on.
Drip holes around the top, thru the edge of the lid and the edge of the tub. Then put "zip-ties" through the holes to secure the lid to the tub; and secure it closed. I thought it was so much better than straps, tape, etc.
