I gather your response was mostly in reference to food delivery services. The OP was suggesting this as a platform for more than food, which is what I'm primarily interested in. It's retail shops that are less experienced with and newer to the idea of everything needs to be delivered right away that I'm curious about. Having said that, our original focus was on furniture stores who have always had to deal with fulfillment and delivery. The type of delivery is very different in nature though -- a 200lb sofa vs a 16oz burrito!
Thanks again.
