Vetsource Promo Codes & Coupons September 2025

Your Vetsource promo code may show as invalid if it's expired, not applicable to your order, or if you're trying to use more than one code at a time. Common error messages include "Invalid code," "Code expired," or "This offer cannot be combined with other discounts." Promo codes on Vetsource are typically valid only for specific dates, products, or order types, and many are restricted to first-time purchases or new AutoShip orders. Double-check that your code matches the current promotion period and that your cart meets any minimum purchase requirements or product restrictions (for example, compounded medications are often excluded). If you copy-pasted the code, make sure there are no extra spaces. If the code is still not working, try clearing your browser cache or switching devices.

Pro tip: Always check the promo's valid dates and product eligibility before checkout—most codes are single-use and time-limited.

No, Vetsource only allows one promo code per order—offers cannot be combined. If you try to enter more than one code, you'll see an error like "Only one coupon can be used per order" and the checkout system will reject additional codes. This is a consistent policy across Vetsource promotions, including instant discounts and AutoShip offers. To maximize savings, choose the code that gives you the highest discount for your order type.

Pro tip: Review all available codes before checkout and pick the one that best fits your purchase—stacking is not allowed.

Yes, Vetsource promo codes are often product-specific and may only apply to certain medications, brands, or categories. For example, some codes are valid only for Heartgard Plus, NexGard, Metacam, or Previcox, while others exclude compounded medications or AutoShip orders. The promo details will specify eligible products and any exclusions, and you may see an error like "Code not valid for selected items" if your cart doesn't match the requirements. Always check the fine print for product restrictions and eligible order types.

Pro tip: Before applying a code, confirm your items are listed as eligible in the promotion details—this avoids checkout frustration.

Some Vetsource promo codes are designed specifically for AutoShip or recurring orders, but not all codes apply. For example, you might see offers like "Save 10% on your first new AutoShip order and then 5% on recurring orders," but these discounts are not combinable with other offers and may exclude certain products. Other codes, such as bundle deals or first-order discounts, often state "Not valid on AutoShip orders." If a code isn't working, check whether it's intended for one-time purchases or AutoShip, and look for messages like "Discount does not apply to AutoShip orders."

Pro tip: If you want to use a promo code on AutoShip, look for codes labeled specifically for new AutoShip orders—regular codes usually won't apply.
