Digital BW, The Print

You can even softproof your images by getting the profile of the 
individual printer they are using at that particular store. You do this 
by going to the web. Costco's, among others, are here:

I use this quite often for quick prints by uploading through the web 
then picking up at the store (Costco). It's quick and easy, the results 
are great, no muss no fuss and cheaper than I can print at home.
