I ended up going with a Uline box for 20x24 and an Archival Methods 16.25 x 20.25 "Trans-Port" case which got a lot of praise from a friend of mine.
I am super tight on space at home and my new office so I needed something re-useable for now. And yes, I agree with how Anne and John ship prints, I kept the box to my 11x14 I bought from them, will create a variation of it once I start mailing prints for sale.
Thanks for all the replies folks, I hope I started a worthwhile topic for others to glean from.
