Im probably not contributing much to this thread but Ive been ordering from them for 3 years or so down in Wichita.
Not sure exactly where you live, but in Wichita at least if I order at least 10 bags of food they deliver here once a month. They charge sales tax plus $5 shipping. Maybe on the shipping deal Im in on an older program or thats what they charge since I live in Wichita. Not sure.
Been ordering the Tuffy's gold. My buddy has 3 short hairs and a Mastif so he takes the bulk of it.
Anyways, never had a problem with them. Im not so sure you need to order a full pallet unless you live outside of a large metro area...ie KC, Topeka, etc as Im pretty sure theyd send a truck there to their regular customers at least once a month.
If you want the higher end of Tuffy's they have Nutrisource as well.
Ive never personally ordered through their website. Becky always calls me before they send a truck to Wichita for the month to see if I need anything. Maybe if you call them up you can get a smaller batch quantity.
Anyways Id highly recommend going that route if you have a person or two you can trust to pay you when the order ships. Or just see if you can get a 10 bag minimum and order for yourself.
