Jeppesen Airway Manual Express
California Annual Subscription (6 Issues - evey 56 Days) #AEXJCA43 $142
It sounds like the one from ipilot is the same thing, but I cant imagine how they can sell them for that much cheaper.
Either way the Jepps Express packs are a complete set of charts for the area for 56 days. You toss all the old ones.
Here is the quote from the Jepps web page
"Airway Manual Express
Jeppesen's Airway Manual Express is designed for the pilot who wants a completely new set of Jeppesen Enroute and Terminal Charts every 56 days. With this service, there is no need to file revision. After the 56-day cycle, you simply discard the old charts and begin using a new set. These chart packets are available as a 1-time, 56-day set from Jeppesen, your favorite pilot supply shop, flight school or FBO. You may also subscribe to our annual subscription service for six issuances. This service is very popular with IFR students, CFI's and pilots who fly in small geographic areas or occasionally fly outside their primary area of operation. Airway Manual Express is conveniently segmented into easy-to-use geographic regions. You purchase only the coverage(s) you need. (A 28-day update is included when purchasing an annual subscription.)"
I tried adding a link to this part of the Jeppesen web site, but It would not work.
