Last item, bought by several customers at the same time.

[Bartłomiej Bury]

Hello,

I have such a problem, when customers buy at the same time, the same item that is the last one in the inventory.
Presta does not validate and inventory go down on the miuns.

Presta unfortunately allows such a situation where everyone buys the same last item,
 the one who first approves the order should buy (the rest should get a message like "out of stock").

Is there any way to solve this problem?

I know that there is a plugin (https://addons.prestashop.com/en/stock-supplier-management/21707-temporary-product-reservation-lonely-stock.html) 
with the reservation of items but this is not a good solution in my store because I have very big traffic. 
Abandoned baskets and the number of goods reserved for it would slow down or they did stop the store.

Do you have your store and products configured to deny new orders when product is out of stock?

I've same condition, but in my case I think my OPC module was the cause. But I'd like to know if anyone have another experiences
