They're implemented as best I can.

Liquor compliance has me stuck to one payments processor that doesnt like bitcoin. After spending hours arguing with them and even having Jack Mallers reach out to help set it up, I've given up with them.

That said, you can check out with bitcoin on my site. It has its own checkout flow and a bit less customizable orders via zaprite, but I also process a ton of bitcoin orders from people who just message me to make a custom pack.
