About
- Input: Template:Vbzcart, Template:Vbzcart, Template:Vbzcart, Template:Vbzcart
- Output: Template:Vbzcart (delete/insert)
- Notes: Later we might refine this into a way to view unavailable suppliers as well... but that's very low priority, and it might be better to have a separate table for it anyway (keep "active" operations fast).
