The Orry Mill review for Early Bird: Preorder & Restock

Early Bird fitted the use case I had perfectly. It can handle out of stock requests but more importantly for us, it allowed me to target individual products and create campaigns to build pre sales. I had full control over how this worked and the customer support is second to none. We have been using Shopify and associated apps for 6 years now and Early Bird have been one of the best to date. Highly Recommend.
