"We've always had a relentless drive to keep your costs low. In fact, you haven't had to pay a commission to buy or sell Vanguard ETFs® for almost a decade.

Today we expanded that to include about 1,800 ETFs (from a universe of around 2,000) from more than 100 other companies.* Why? Because at Vanguard we're committed to making sure you have your best chance for investment success."

Interesting.
