I have a surplus of 120 film that I\'d finally like to get developed today, but I don\'t know where to goI have a sneaking suspicion Walmart and CVS aren\'t going to handle medium format, and it doesn\'t look like Penn Camera does developingHelp.Since I no longer have a local pro lab, all of my 120 film goes in the drop box in Walmart They send all the weird stuff to Dwayne\'s Photo in Kansas, which is one of the better labs in the country In any case, the print film processing isn\'t that great-you get back tiny prints(about 3.5 square)The negatives are always clean and scratch-free though(and sleeved), and the price is right-under $2 for 12 exposures, as best as I recallToss the prints, and you still have a bargain on negatives that you can scan and print to huge sizes Slide film is another storyIt\'s also clean and scratch-freeI request mine uncut, and they send it back to me rolled up and sleeved inside a cardboard tubeThe price is $4.88 for 120, and I\'m told that it\'s the same for 220(although I don\'t use 220, so can\'t say for sure) In both cases, the advertised service time is two weeks, although mine usually comes back in a week EDIT: Generally, I just drop the loose roll, sealed shut with the seal strip, down in the bagI\'ve never had an issue doing this over the course of several hundred rolls Occasionally, I\'ll slip the roll back down into the foil wrapper that it comes in from the factory If you\'re really paranoid, medium format film will fit in two standard 35mm film canistersJust put them together and tape around the middleWhat you\'re doing certainly won\'t cause any harm, but in opinion it\'s probably overkillIf it gives you peace of mind, by all means keep doing it.Other related question
