PFD has a free shipping deal today, no minimum or weight limits

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

Thanks! I typically order from Pet360 but this site has better prices!
But they do offer free shipping on $50 orders or over....

Says mine are $33 and $159 not $23 and $85....

Looks like the free shipping is only if you sign up for automatic shipping

They also changed the prices since this morning.

It didn't make me sign up, just asked me to and I declined at checkout.
The prices jumped on the food since this morning...Too bad I didn't order any rat food this morning (was going to check my supply at home first). *sigh*
