The choices are a bit weird, too. The "prints" selection does not list scanned/digital RA-4 prints which 99,999% of the labs do and is the most common option, but does list optical prints. As the most common selection is missing, this may lead people to select "Machine Optical" even when it is not true, and then your index will tell people that most of the labs do optical printing, which is a problem for someone looking for labs that do optical printing which is a VERY rare special service nowadays...
