Not sure what the "wreath" part is... but you can get sterlite/rubbermaids/sweaterbox/shoeox bins at any walmart or target store
The Sterlite Wreath Box is a particular size of box made by Sterlite. It is 27 x 27 x 8 which is larger than most other boxes of similar height. It is a perfect box for relatively slender snakes in the 4-5 range or for Ball Pythons.
I have checked all the local obvious places (Wal-Mart, Target, etc).
