My wife was "cleaning house" and suddenly plopped a bag of undeveloped 35mm film in my lap. Most are 24 or 36 exposures, along with 2 disposable cameras. I'm a member of Costco, so that may be the cheapest way to go, but wanted to probe the membership to see if perhaps a mail order outfit might less expensive ? No real urgency to complete this order. Thanks for any comments !
