Efficient box/package size for two adult Black Rat snakes?

[krazyblurtz]

I'm trying to get this shipping cost with shipyourreptiles under the $98 estimate they gave me..
..I've shipped three adult ball pythons before and it didn't cost that much.

Anyways the male is 4.5 ft the female is 5.5 ft.

What size box or set up would you prepare for this?

It really depends on how you are packing them, and where they are going. You don't say when you experienced cheaper shipping prices; but they seem to go up at least yearly (if not more frequently).
A 12x9x7 would probably be a little small - I don't know SYR box sizes; but the next size up that I use is 14x12x8, which would easily fit those snakes.
