FYI - if you live near Denton county or don't mind making the drive - Donald Paddock Feed Store in Krum is selling 50lb bags at a fairly reasonable price:

1 Bag - $7.00
1/2 ton (20 bags) - $6.75
1 ton (40 bags) - $6.50

What sucks though is the corn is in paper bags!! I hate those, but at 6.50 per bag for 1 ton - I'll deal with it.

By the way, they told me they'll be going up in price very shortly.
