Hey guys, I was looking around for the cheapest possible Native Earth 4018 and came across a site called www.pet360.com (which I'm pretty sure is a Petfooddirect company).
They currently have 5 bags of 40lb 4018 for $132.95 (with free shipping):http://www.pet360.com/product/9093/n...nt-diet-40-lbs
There is a PFD coupon that works and will give you 10% off (PFDSAVE10) which brings the total down to $119.65. If my math is correct that's about $24 a bag ($.60 a pound) which isn't great but isn't too bad for being shipped to your door.
I personally have not ordered from these guys yet, but they seem to be part of the same company as Nationalpetpharmacy.com which is a legit company.
Just wanted to share.
