About Heartland Vet Supply

Established in 1981, Heartland Vet Supply provides veterinary drugs, pet supplements and animal health products for horses, dogs, cats and farm animals. They stock thousands of products from leading brands such as Merial, Zoetis and Bayer. You can shop for both prescription and over the counter products, such as flea and equine dewormers. All pharmacists are qualified to work to FDA standards. Heartland Vet Supply's online ordering service delivers products straight to your door, with bulk discounts available if you wish to buy in larger quantities. They have a licensed pharmacy which is part of the National Association of Boards of Pharmacy (NABP) (this ensures access to regulated and safe pet health products in your own home).

How Do I Apply a Promo Code at Checkout on Heartland Vet Supply?

  1. Choose a product: Head to a product page such as 'Interceptor Plus Chewables for Dogs' and select the dosage and quantity. Click the red 'Add to Cart' button.
  2. View cart: Once you've added the product, click the red 'View Cart' button to access your cart.
  3. Apply promo code: On the Cart page, scroll down underneath the items. Find the 'Enter Coupon Code' section. Paste your code from DontPayFull into the box and click the red 'Apply' button next to it. The discount will be applied above the subtotal if the code is valid.
  4. Checkout: Click the red 'Proceed to Checkout' button on the right hand side of the cart page. The discount will still be visible during checkout. Heartland Vet Supply does not have a rewards scheme or stackable coupons at this time.

What should I do if my Heartland Vet Supply coupon is not working?

  • Look for brand and product exclusions: Selected discounts exclude prescription drugs, vaccines or brands such as Merck or Zoetis. Read the terms thoroughly before using any code.
  • Double check auto-ship orders: Some deals don't work with auto-ship orders, or only work on the first auto-ship order. Switch to a one-time order to test if the code is applicable.
  • Look out for minimum order amounts: Most codes have a minimum spend, usually around $49 or $75. Make sure your basket is eligible after any discounts or automatic discounts.
  • Apply the customer service workaround: If a code from our page has failed but meets all terms, contact them with a screenshot of the offer and they may be able to apply the discount manually or give you a new code.
