I barely even remember entering a code for free supplies from Valley Vet Supply. I just came home to 1 full jar of Probios probiotics ($16 value at feed store), 1 brimming full jar of Goat's Prefer Probiotics ($13 at TSC), and a ketosis drench ($7 at KVSUPPLY.COM). All that for free, plus free shipping! I now have three brand new jars of probiotics, including the one I just bought. I am a loyal costumer now! I just thought that was really cool, I love free things!
