Thanks! I was ordering from PetFoodDirect.com and it was costing me over $70 to ship. I just checked and to get 5 bags of Harlan it was $156. I was seriously considering hog feed at the local Tractor Supply when I ran out of Harlan, but once I looked at the National Pet Pharmacy site with $4.95 shipping, the cost difference between hog feed and rodent food was not that significant (to me anyway). Also, it saves me a trip on the weekends and I can still use it in the food hoppers of my lab cages.
