Get a free sample of Better Than Ears Plus dog treats from Walmart. Look for the yellow “Get a Free Sample” button near the top right of the page to get to the form to fill out. It is optional to fill out a short survey after you receive this sample. You should receive your sample within 4 weeks and I’m guessing it may include a coupon too.
Update 8/16/10: Received my sample of one “pig ear alternative” plus a $1 coupon (expires 12/31/10)
