I don't know who the genius is that came up with this lame idea, but they need to be fired. If you as a seller are so dang lazy that you can't be bothered to take something to the post office, please close your business down.
This shipping service adds DAYS to the delivery time. If an item is actually mailed at a post office, it will arrive a minimum of 3 days faster than if you use the lame UPS Mail Innovations (and there is NOTHING innovative about this service AT ALL).
UPS isn't even a good delivery service with their own system, and this one makes them look even worse. Do yourself and your customers a favor and stop using this service.
The postal service WILL pick packages up at your business for free - just like UPS. The difference is that there will be no delay or added shipping time, because lame UPS is not involved.
