I bought a ten pack of Double Disc Memorex DVD cases from Staples. I am working on a wedding DVD with footage I took as well as footage from another camera. I captured over 3 hours and the other guy got maybe an hour. I put his stuff on 1 disc and I am finding I will need 2 discs for my material. When I opened the cases I bought I noticed they had a place for a hinge in addition to the 2 slots offered. I was wondering if anyone knew where to buy just the hinges. I only need like 10 or so but I would be willing to buy a 50pack. Thanks.
