Not sure how long it'll last but today they have free shipping on any order.. No minimum, no weight limit, and no code needed. I just ordered a bag of harlan aspen and sani-chips. I may order a bag of native earth rat chow too.. But I'll need to check my supply first. I'm considering switching all of my snakes over to aspen (my rats and some snakes are already on it) so any time I can get free shipping on an already good deal is great.
Here's a link to their site.
For reference, their prices are:
Shredded aspen 4.38 cu ft $9.30
Sani-chips 2.2 cu ft $9.39
40 lb Native earth 18% $23.99 OR 5 pk (200lbs) for $85.99
