What you will notice is that the "bid" and "ask" prices specify a quantity. (At least they do on Etrade.) If you are trying to purchase a bigger quantity than the numbers of shares they give, you may well get locked out. You may have to settle for a smaller number of shares to complete the purchase. Also if you try to buy a larger number of shares than what's in the quotes they may be unwilling to sell them to you for the quoted price even if more shares are available somewhere.
