Stellar Delivery Date & Pickup

Unfortunately we had to delete this app after trying to get it up and running. Customer support was good. But the App only allowed date and time picker to appear on the cart page. We needed it for the product pages. The add on app that cust supp recommended was in JSON format and screwed up our order summary pages (additional details - which was supposed to list delivery date and time). Since there was no way around it.. we uninstalled it. Hope you can fix it as it sounded really promising when we decided to install it.
