large amount of aspen were

I have 14 snakes and changingthe cages is not really a pain but i can only get (currently) aspen shavings ( like the pine for rodents) in a 8.0 cubic bag. I adopted a snake recenlty and the lady gave me a 10 liter bag of he reptiles aspen ( I call it grount type cause it los like small splinters). I can not locate a store in delaware that carries the larger bag of such . Trex list a 160 qaurt bag and ( i been told it about 6 cubic ft . ) I have not found any other info on the product or were I can locally get it . ( the current aspen is really dusty) I looking for possible east coast supplier and rouglhy what a xcubid ft bag would run .. befoer shippnig . also beanfarm has what i want but they saying it cost more to ship it than the pruduct worth..
I don't mind making a call next week to some retailer/distruber to look for this ..

I buy the 1250 cu in. made by katee , try them at kaytee.com they are out of WI
