Pros
Corporate support is fantastic. For the first year or so they will send someone out periodically to check in and see if there are any areas that they can help with. It really is a community of printers that (for the most part) help each other out and want to see each other grow.
Cons
Can be a bit competitive internally. If you have several Francises that are close to each other, they can get blinded by fighting for territories that they forget about about the Non AlphaGraphic coipition out there. Some of the corporate standards can make it difficult for a shop to break out of the "copy shop" set up and move up into larger printing. It almost feels like corporate wants everyone to be large format printers that also do business cards.
