So at the one day I was standing in the store and I wondered, is that really the best price for this product around here?

And as I was using Android before I figured, hey, I could create a client for that and participate in the Android Developer Challenge. While the idea was good and ShopSavy, basically a 100% implementation of what I intended to implement did win. Unfortunately I was too conservative and pricerat.com did not make a cut. It was a very interesting project nevertheless and I created plenty of documentation :)
