I think Costco still operates an optical printer here. Once in awhile my wife drops off snapshot film
from her little 35mm Point n' shoot and it comes back in the traditional look. The other method basically contact prints LED's onto the RA4 film, which comes out a lot different color-wise. They also offer cheap digital printing from digital files, but not with the same machine, but rather some
kind of automated inkjet system. I haven't paid much attention because I do my own RA4 printing, mostly large format.
