ornament & crime is a post-capitalist product of the sharing economy.
As such, it is neither manufactured nor sold by a Single Entity. However, there are several individuals who are willing to construct an ornament & crime modules for you, to order and/or on commission, and there are a few vendors who construct small batches of ornament & crime modules and offer them for sale prospectively.
For anyone wishing to buy or commission a pre-built ornament & crime module, we recommend that you undertake a google search to find posts on internet forums such as the stupidly-named but very popular MuffWigglers forum about Ornament & Crime builders and/or vendors. Pay particular attention to reputation and positive reports (although at the time of writing we are unaware of any bad reports about ornament & crime builders or vendors).
