I have been ordering Heartgard, flea medicine and worming medicine for both cats and dogs from them for MANY years. I always found them friendly on the phone. I never had a problem with any order... and NEVER had a problem with the quality of the medicines. They have saved me a ton of money since I can check a heartworm blood test once a year then save money ordering the medicine. I have been very happy with them and find any comments about "suspicious" meds totally misleading and likely a competitor!
