By uploading digital shots for printing, their "new" rate is $0.16 for 4x6. Oddly enough, I don't remember seeing the pricing board in the store this weekend (with film processing fees). Suggest you call your local store, and ask. Costco is MUCH better these days at sharing their pricing informtion by phone
Just back from Costco, I went on my lunch break, surprisingly unbusy. Roll of 24, 35mm, 4x6, with doubles is $5.19 plus tax and they could have been ready today if I wanted them. I said I'd pick them up tomorrow.
We have been impressed with Costco, both with their quality and speed of service. We developed about 500 photos from our trip in September (mostly using our Photopass CD) and they turned out great. Was ready within about 5 hours. I did have to bring the CDs in to prove that I had the copyright to it.
I've been using the Costco online photo service...Really fast service!!!
I upload the pics through the website and in about 1/2 hour I usually get an e-mail to tell me my pictures are ready for pickup. One time it took 15 minutes. Still 16 cents per print.
