Etrade. Don't use market orders, limit orders only. If you're uncomfortable with limit orders think of them as a crossing point. Currently the price is .820. If you placed a limit order for .82 it would execute automatically. If you put a limit order in say for .08 and it goes down to .079 it'll execute at either $.08 or $.079 depending upon the bid size and how many are available for sale at that point.
