Addicted to this game

I am really enjoying this game. First game I go to when I turn on my iPad. Love being able to upgrade and improve my shop. As the levels increase, it becomes a very challenging game which is great. It challenges you to keep your customers happy, your ability to manage multiple events, speed, etc - very fun! To the creators: could you decrease the number of diamonds required as time passes on re-stocking gift key chains and the super stereo? For example, to re-stock my super stereo it costs 12 diamonds when the clock begins (12 hours?) . I am now at 1 hour and 30 min. to re-stock and it still costs 12 diamonds. Could you decrease the requirement as the clock ticks. . .so for example could it now cost me one or two diamonds? Thanks for a great game!
