Player places the vending machine and lists products and prices as usual. But the items are not added to the machine, the raw materials are. As long as the owner of the vending machine has the blueprint researched and a workbench of the correct level has been placed (anywhere in the base? near the vending machine? inside the machine? ¯\ (ツ)/¯ ) it will create the item 'JIT' until the resources are exhausted.

The ability to use more than one currency at a time in one transaction would also be interesting. If players could charge wood and metal frags for finished level 2 gathering tools, the machine would restock itself.

The ability to use unused items as currency. The player who placed the vending machine does not yet have the blueprint for Salvaged Axe, and they have elected to accept higher-tiered items as payment in exchange for <#> available items of the buyer's choice.
