Amai PreOrder Manager + Notify

Great app! There are very few plug-ins that support Pre-Orders on Shopify. When your a new business, launching great new products, sometimes you are waiting for the next batch of inventory to arrive. There is no flexibility with the normal Shopify features, so Pre-Order Manager helps you quickly setup and communicate to your customers that they are pre-ordering and when they can expect their product to ship. So far its the best solution I've seen and works as advertised. I recommend to anyone launching new products!
