Only allow available inventory to be added to cart

[Androgenonsense]

Today, users can add any amount of an item to their cart regardless of how many are in inventory, and only get an error message at checkout. This should be updated so that the item counter toggle on the item page can not be moved above the available inventory. I.e. if there are 5 left, a user should not be able to move the counter to add 6 and add to cart.

Yikes. This seems like inventory 101 and should be fixed asap

Unfortunately, Square is aware for some time and has yet to fix this very basic request. I posted recently about it as I would like to purchase the abandoned cart feature, but not until Square gets this inventory thing fixed...
