Well, not really.
So, every month, I allocate X dollars to eating out for lunch, with the goal of taking my lunch at least 3 days a week.
If I don't eat out those three days, that evening, I send the cash straight to Vanguard, buying a fraction of a share. It gets it away from my hands, I'm less tempted to eat out with it the following week (Well, I have a meal left from last week...), etc.
Anyone else do this? My Vanguard transaction history is long, but I figure if that aint DCA'ing it... nothing is! :-D
