The ability to print from anywhere at any time. It's easy to use and I love that it keeps my work safe in the cloud where I can access it remotely. I don't like that you have to pay if you want more then 50 prints or if you need to make large prints. If you are looking for an inexpensive way to get your work printed without having to go through a printer store, this is definitely the place! My clients can order their artwork online and have it sent to them via email or they can pick up their orders during business hours.
