PST Pool Supplies review for Shopify Collective

This app is great overall and has helped us increase sales with new products that we otherwise would never have been able to sell. But there is a massive bug in this app that FORCES products to enable "sell when out of stock". Even though suppliers are sending 0 in stock for items, this app allows customers to still purchase!! It's incredibly frustrating to not give us the option to turn this off for Collective products!
