retic substrate

[scottyy]

what substrates other than newspaper will work well and cheaply?
Right now i have my girl on newspaper in her little bin. i realize she will outgrow that fairly quickly as i can already see that she is growing. When i upgrade her to her lifetime enclosure i want it to be all natural with some sort of a repti bark or something that looks nice because this is my only snake (for now) and i want her cage to look nice and would be willing to put in the extra money. Also if other substrates like mulch (with no dies) would work because you can get a big bag for fairly cheap and sense i will need a lot of it a small bag of repti bark for 15 bucks or something like that would take a lot to fill up a cage of that size.
