I hated Repti Bark. It was extremely dusty and lumpy. My BPs would have pink spots and dents on their bellies from their weight resting on the hard lumpy pieces. It also was weird about humidity (not very absorbent), and doesn't hold heat well due to the large air pockets.
I use cypress mulch (double-milled is best), or shredded aspen, both of which are much better at holding humidity and warmth. They are also softer for the snakes to lay on (especially the aspen). I think they both smell pretty good. The aspen is easier to see poo on, especially if you've got a small snake that's making small poos. As was previously mentioned, you can buy these bulk for pretty cheap from pet stores, farm supply stores, and lawn and garden stores.
Good luck with your girl; that was a pretty sweet deal!

okay sounds good. I want to hear a couple of other's opinion. If its widely not recommended then I will change.
