A little high????
Are you being sarcastic or funny?
You can't be serious??
I'm guessing he is serious. To some (many) people $100 is a lot of discretionary spending. I think Jamie has been very thoughtful in how he's gone about raising prices. One of the things that makes our fanbase great is the low cost of entry. Raise that entry cost and you lose numbers, pretty much automatically.
I think the revenue problem lies not in the bottom bracket entry costs, but more with the mid-tier and above.
Edit: Also with marketing in general. As others have said, have a century club have some sort of participation in a fundraising goal, etc. Not just a generic "send us money" plea - get creative.
