Stellar Delivery Date & Pickup

I've used this app for almost a year now. I ship greeting cards and gifts. For a few years I just took in the orders and shipped them as they came in. I knew it wasn't perfect. But I did install this app and it definitely helps customers buy now, select a future date, instead of waiting for a future date to place the order (and probably not come back). The app is stable and the one time I needed help with the app they were online and quick.
