Local Pickup Plus for WooCommerce

Hello, I wanted to know two things:

1) Can I indicate the availability of each individual product in each store?

2) once the sale is made, is the availability of the product in the point of sale where the collection was made automatically deducted?

3) Can the customer who decides to collect the product from the store from the site decide whether to pay directly to the store or does he have to pay on the site?

Thank you very much!
