Just jumped on to this thread. I tried to order some tonight and saw they were closed so I ended up finding this forum. I have not tried the purina but it looks pretty decent. I did find optimal from a store in Iowa but the shipping by UPS ground was about $70. If anyone hears that they are going to reopen or even under a different name, please let me know. I think one thing that stood out to me was the "freshness" of the feed vs what I had previously purchased at a local farm and home store. If by chance anyone from optimal is on this thread, feel free to private message me.
