Deb,
That has me thinking the 5 ton minimum is true.  That's 200 50# bags!!!  i don't have access to any feed store around here that could carry that much of one brand of feed.  it makes me think it's more an effort to eliminate the competition, but that might be giving them too much credit.  perhaps things are just a little bumpy right now.  i don't understand it but this is the first thing i haven't flipped out over!!!  Good idea to find other options.  Seminole is a pretty good feed, isn't it?
