Whenever I order from ERXonline, as soon as I'm through I call them directly thereafter and request that my meds be sent through Speedscripts, they have never had a problem with doing that for me. I prefer SS over PP b/c they seem to be faster and more efficient for me.
As far as your problems go, is it possible that the process of your order got slowed down due to the weekend followed by the holiday? Just a thought...
