The Staples website is the primary online outlet for purchasing refills for ARC calendars. The ARC line of products is part of the M brand, which is owned by Staples.
The ARC notebook and calendar system was designed by Staples as a customizable planner that can be refilled as calendars expire and events pass. Staples offers refills for the ARC system on its retail website, as of 2015. One of the packages offered there includes 12 months of calendar planner pages, as well as monthly organizer tabs and planning pages, printed on heavyweight paper. Other pages on the retail site offer related products such as dividers and business card holders that can be added to the ARC notebook.
