Purina is going to ship me two bags of MVP directly, since it is a special order from my local Purina Dealer (they don't stock Purina fish foods). I will have to continue to special order it next year if I want to keep getting it.

I appreciate it that a manufacturer will step up and make things right. Thanks to Bob for the help!

But, like I said, most casual users won't know any difference, so won't complain. A guy at the local feed store last year suggested I feed pig food instead of sinking catfish pellets they didn't have because "it's probably good enough to work". People are so misinformed, even sellers.
