From the ad: "†The Vanguard 500 Index Fund has no up-front sales charge"
Yeah. And no back end sales charge. And no annual sales charge. And better tax efficiency.
Oh, and once you have over $10K (which shouldn't take that long for an average Mustachian to accumulate), Vanguard will *automatically* convert those shares tax-free and sales-charge-free to VFIAX. With an ER of 0.04%.
