Question Description

I'm having difficulty understanding the difference between these three types.
Could you elaborate those in the documentation? Thanks!

Also, the Readme says there's inventory management included, but I can't find managing quantities anywhere.
Does Litecart support managing inventory, e.g. displaying to users how many items are available and optionally how many have been reserverd/bought? And when there's 0 items left then disable buying that item.
Would be helpful feature for simple guest registry where guests can see which items are still available.

Code Snippet (optional)

Checklist:

• I agree to follow litecart's Code of Conduct.
