I'm getting mine from a family farm/feed store, who gets it from the mill right across the Alabama border. They go thru probably 30 tons of feed a week, best guesstimate? Maybe more. SO they've got a great price to start, my pricing is buying 500# at a time, paying cash. Actually, its cheaper than if I bought straight from the mill. If I use credit or buy in smaller quantity, my price goes up to almost $18 for the feed whosse tag I photo'd, and about $13 for the layer formula.
Are you south FL or central FL? Central FL has at least two feed mills with quality products at reasonable prices. I'm not aware of any in South Florida - shipping is going to kill you there.
If you were central Texas, I'd recommend West feeds. Good prices, great numbers.
