I've noticed it takes a while for the MM's to route orders. If you use Etrade to hit ETRF or Ameritrade to hit ATDF it is instant, but if you use ETRF to hit NITE or UBSS it takes a while to route teh order to the other books as ETRF wants to fill it internally since they only charge $9.99.
If you have professional trading software you can sit on most of the books or remove from them.

My advice if you REALLY want the shares and don't want to get stuck paying commission for a part fill is put your limit price a couple ticks higher then what you see on the offer.
