Unfortunately, I probably won't be buying anything directly from Vanguard for awhile. After I rebuild cash reserves this year, I'll be shoveling all I can into the 401(k) at work with the intent of getting AGI below the threshold where I can qualify for the Earned Income Tax Credit. $3,300 is quite the incentive.
It still will be going into Vanguard, but filtered through the 401(k).
