THC for sale after table purchase

I thought I saw the THC upgrade in the store at one time, but it is not listed anymore? I purchased my Pro and am using it, but have thought about adding the module. Can it be purchased separately now?

Copying @langmuirsystems

It won’t be a problem but you will be charged a bit more. They have lots of things they sell that are not listed separately: CPC port wire for Hypertherm and I have heard they may sell a USB isolator unit.
