I've tried three large retail store photo labs over the years for printing pictures and have not been thrilled. The prints came back too grainy or discolored with burnt red and/or yellow tones. A few I've put in frames for a while but ultimately tossed those photos in the garbage, which made me sad because wasting time, money and materials bugs me. I recognize that I am particular about quality and color. I think others are as well.
Here's the great news.....these website links take you to print labs that professional photographers use and you can too!
If you care about the picture, you will want to care about the quality of the print. Especially if you are enlarging an image than high-quality printing is important. Each of these sites offers a wide variety of products.
My professional photography interactions have been with mpix and simplycolorlab. I have been very satisfied with the products from both and had exceptional experiences with both photo labs.
For Christmas Cards and Party Invitations, I have been downright delighted with these web businesses:
