Pickup & Delivery Buddy , 16 reviews
I chose this app from among the many pickup/delivery scheduling options because it made it easy to enable pickup scheduling on just a single day one month in the future which is the nature of our "buying club" Shopify application.
Kyle, the developer, was very responsive in resolving any issues that turned up and in helping me to "stretch" the app beyond its intended limits. It saved us a great deal of correspondence effort by enabling buyers to sort themselves into 15-minute pickup slots, each with a set order limit.
I would only give it five stars if it could fully sync with the Shopify database such that changing pickup times manually in the app also changed the tags appended to the order, and vice versa that editing or cancelling orders within Shopify propagated through into the pickup calendar within the app. This may well be beyond the capability of *any* available pickup/delivery app, or maybe even technically impossible for reasons I don't understand, but I would challenge Kyle or any other developer to make it happen :-).
