That is the only way I could have jumped in on this stock. I started buying at $1.85. My commission fee is $7 and I take that into consideration when I am calculating my profit if I were to sell. I wish I had more money to buy big but some of us have to take it 1 step at a time. So far my cost average of the amount I own is about $4.35. I think that if I were to sell now I could consider that a pretty good profit.
The commission isn't the problem as long as it is gained back. But yes, if you buy small batches of shares, it will add to your total cost per share. But for trading purposes if I start the day off with $100 do some trading end the day with $140 after all commissions are cover that is REAL CASH in your pocket.
