Well, its a bummer none the less. I went a different route even though I don't live too far from the cages in question, I liked my experience with the Constrictors NW Pro-Lines.
My boa is livin the dream.
Personally I think you WILL get your cages before you move but I just feel for you and anybody else who is so excited to get new a snake, or a new setup and then ends sitting in limbo.
You deserve an e-mail, text or brief phone call.
