Moondog,
I can't speak to any specifics, but I'd ask you to keep one thing in mind. PodDisc sounds like it's some big company, but it's Steve mailing the stuff out of his basement. Turnaround time is going to be a little longer than Amazon.
It's really amazing actually. Amazon ships pretty much in a couple of hours and depending on how far away you are it takes a couple of days. I remember (shit I sound old talking like that) when most catalogues switched from mail order to 800 numbers. Shipping time went down from 6-8 weeks to 2 weeks.
