Do you use an online printing service?

Hi-
I am anticipating a lot of printing come springtime and am remember the nightmare of sending and making delivery appointments with everyone who orders prints. I am wondering if any of you use an online service that you upload your images to and then they print and ship them? For weddings we use pictage.com and I am looking for a similar service that can produce professional results for other events.

Obviously I am worried about print quality - i know my lab and they know me. However, the attraction of online credit card ordering for customers is huge.

So....anyone use an online printing service? Thanks.
