Billshrink.com is going to bring a never-before-seen level of transparency to consumers looking for the best credit card offer. Think of it as a turbocharged dashboard for navigating the credit card market. The site launched earlier this year as wireless plan comparison service, but with personal debt at record highs and personal savings rates at record lows, the credit card vector is potentially even more important and useful tool. I sat down with CEO Peter Pham yesterday as he showed me the actual website in action.
