Absolutely. To answer your question:
Putting in multiple buy orders sets a level of security for someone. Even IF I know I can get shares as cheap as I set my lowest buy-order in for, there is also a risk in not getting those shares at all (i.e. "gap up", buying pressure, etc). Profit margins on thousandths of a penny are not worth the risk (to me) WHEN a stock rises... especially one such as ANDI. To me, I would rather risk putting a few extra dollars in to something knowing it will continue to rise.
It is better to have tried and failed than to have failed to try.
Hope this helps!
