> So you believe a company can charge $99 for a yearly service and then say "by the way, we may increase prices in 30 days if we decide to do so." So what happens to the $99 I paid?

Uh, it would still be paid? Price increases only apply to new billing cycles, not retroactively, so I don't understand what you're getting at here.

The point is that it's incredibly easy — and relatively standard — to incorporate the possibility of changes into a contract.
