Order out of stock products with LIMIT

[Boguskac]

Hello,

I want to setup something like the "Allow order when out of stock", but with limit. 
For example, i would like to setup the  product to be orderable up for 3 pieces, even if it's out of stock.

No, It is not  good the idea to add 3 to the original quantity!
I have a module where i can set the maximum quantity (orderable when out of stock) for every product, and i want to display it separatelly also for my customers.

Thanks

Which module do you have?

It's not a simple requirement.

You would need to create a module that hooks to New Order, and have it disable the out of stock ordering if the product is down to -3 stock.

You would also need to prevent people from ordering 2 products if the current quantity is down to -2 (or any similar combination that would result in stock lower than -3)

The above would need to happen in the add to cart functions (create an override for Cart.php)
