I’ve taken that into account (and actually, 1.7 is a very kindly markup – I’m sure you know that big retailers like WalMart generally want about 3.0 or better, or they won’t even sniff your business). Depending on volume, at 1.7 I think the actual retail might go below $30US.

They charge $99, but it works very well in my experience.
