If your on a mac, download this program: http://wetfish.de/software/app-store-expense-monitor/ It will collect the apps in your itunes folder and tell you how much you've spent on apps. Downside is that it only tells you the current price of the apps you have, so it can't tell if you got them on sale or if you paid more than current price and it can't tell promo codes either. So take that into consideration. Of my two accounts here is what it thinks I've spent: Show us how much the program says you've spent.
I respectfully disagree. If I had a Mac this program would be telling me how pathetic I am, something I can happily live without.
In some ways, I don't think I'd want to know! I'd just think, was it really worth it? I'm happy not knowing and carrying on spending.
US$373! Almost enough for a 64GB iPod touch!! However, after exporting to excel and parsing through the data, the app is only looking at the CURRENT price of the apps.... most of which we would have got during $0.99 or free sales. Soo..... working all that out, I can say that I only spent about $280.... sales have saved me almost $100!!! Wow.... now that makes me feel much much better!
