I am such a cheap skate. I have bought very few apps for more than $2. I generally just add anything I want to my 'want list' in AppShopper and watch for price drop notifications.
Stop saying 99 cent or 1.99 cent. Say 1 dollar or 2 Dollar. You are falling into the trap of the marketing people. make a rule. Always look at the price and round it upward. Not that buying a game for 1 Dollar is not a good deal, but seeing every one repeating that 99 cent....
