BillShrink , the startup that looks to help users save money across verticals including cell phones, credit cards, and savings accounts, has just announced that it has grown to 1 million members since its launch in April 2008. Alongside the milestone, the site is also announcing that it has found "$1 billion in savings on everyday bills". That second statistic is a little confusing. BillShrink basically means that if its users had signed up for the top matches generated by its cost cutting tools, they would have saved a total of $1 billion. Of course, not everyone who uses the service decides to change their cell phone carrier or credit card, so the total amount of money saved isn't that high. That said, this is the first time BillShrink has disclosed the size of its userbase, and it's clear that the site is getting some solid traction.
