I send them to Costco. Home is an Epson R2400. It does an excellent job, but is, I suspect, fairly expensive in ink and paper.
The advantage of Costco is price, and the availability of color profiles. If you don't know what color profiles are, then Costco may hold no advantage over other services.
I have for about two years been printing pictures at home. Not a lot, but a few from each trip or event, just to have some in an album. I am coming across more and more people though that have their pictures printed at a store or upload them somewhere for printing. I want to look in to this since I find it expensive to print at home, and I also have problems with my Canon i560 printer. But I need help.... I need some input on what is a good price and also what places are good to have them printed at.
Back in the 35mm days, I had them developed at what used to be KMart, they sent them out, but they always came back great. I have tried WalMart, and did not like them at all.
Any feedback and info will be appreciated. Thanks.
