Yeah the "adding up all my small purchases" thing... I used to roll my eyes at that advice. But seeing the actual number kinda shocked me into cutting back too.

Wait, you agreed to a set price without a detailed list of features? That's asking for trouble... I learned from @nathanr87 that you need to spell out every single thing, like the exact number of pages and what each one does. Any new request after that gets a change order with a new price tag attached. It sounds strict, but it saves so many headaches later on.
