what is a circuit?
Ziggy.. A circuit is a group of 17 books filled with stamps.
These circuits are mailed from Stamp clubs, to other stamp clubs
so that the clubs members can purchase stamps.
If you are a member of the APS, the APS will send the members their circuit books. [ Phil may be able to shed some light on this method ]
The stamps range from 25 to 50 percent of catalogue value
