Well, I don't know about $13.00, but I can get 24-5-11 50% NS-52 3% Fe SGN 15 , 12k coverage 50 lb bag at $19.95. That's about 42 cents per k cheaper. But for me as a low volume buyer, the price isn't what I base my where to buy decision on. That is really an individual store issue. Unfortunatley for me, my store doesn't particularly cater to me and my small potatos operation. Simply said, I get treated better elsewhere on a personal level and customer service basis of valuation. The lower price is an offest to having to travel farther to buy product. For larger volume buyers, I am sure price has much more weight in the where to buy decision. I'm happy to pay a premium for excellent service. I am not happy paying a premium to be treated like a peon, however.
