The small brokerage firm that I was using was acquired by Schwab and we were migrated over last month to their platform.
I've been buying VTSAX whenever we had additional funds left after funding our tax deferred accounts, when I tried to buy $1,000 worth today it goes all the way through the buy process and then returns "We cannot process your order because shares for this fund are only available to institutional customers."
Googling around a bit it looks like you can't buy Vanguard funds directly through Schwab... grr
So, what to do? Go through the hassle and move to another brokerage? Buy a different fund?
