Take $10 off your order of $39.99 or more at PetCareRx.com via code SMART661, or spend $59.99 and take $15 off your order with code SMART322 through 6/30. Plus, shipping is free with all orders of $49 or more. That matches our previous mention as the best dollar off discount we've seen from them this year. Spend less than $35 and shipping starts at $5.99. Note that "internet only" pricing will be adjusted back to regular pricing when you use the codes on prescriptions, but it will get you a better discount in most cases. The coupons will not work on food. There is no sales tax (except NY).
