Stellar Delivery Date & Pickup

I am MD of Stovefitter's Warehouse in the UK. This app allows our customers to choose what day they desire their stove delivering - a service I already know customers think is great (and gives us one up on the competition). Support seem to be always there (in my working day anyway) and usually my emails are answered within the hour (often within minutes). I am using the Product Calendar addon which means I get to specify what delivery dates the customer can choose at the product level. This app still can be improved but I have given 5-star because of the service I have received. Works in both mobile and desktop. JP, MD Stovefitter's Warehouse
