I actually have never bought smartpaks due to the cost. I looked at those supplements but they are cheaper in the smartpaks. Here's the problem I cannot find a multivitamin mineral supplement that is equal to the Smartvite. Honestly I would rather not buy smartpaks. I always feed dinner and I make up the morning feed the night before. Except liquids go in in the morning. And the rest of what I feed is much more expensive in smartpaks so I wont even get the free shipping with just those two.
Edit: I will look at a ration balancer. I will plug that into feedxl during my lunch and see if it works.
