It's a great point. I struggled with how explicit to be about this. E.g. - do you email all the early adopters and tell them how lucky they are they are on a lower plan? Does that comes across as too sleezy? How do you translate this into NEW users? Do you put above the "sign up" button "Buy now before prices increase!"?
Maybe it could be added to the monthly receipts, showing the current price for new users minus their "discount"...

But yea, raise prices.
