The best pages are made by Avery. They are acid-free archival safe - unlike Rolladex pages that may eventually destroy your cards! The trick is to find the 10 pack that has 10 pages to a pack. In Las Vegas, these can be found at Office Depot and are only $2.29 a pack. Therefore, Avery has the best pages AND the best price. Avery also makes a 5 pack with tabs, but this actually costs more, although the pages are thicker.
