“The product and speed of shipment is great, but I can't say as much for your means of delivery which is why the 2 star review. USPS tracking said my package with MEDS for my dogs would be delivered on 21 November by 8 pm. It is now 25 November and tracking has no new information. If it doesn't arrive, I have to spend hoards of time filling out pain in the ass reports to MAYBE get some kind of answer. That alone is enough to make me order from someone who uses more reliable delivery service than USPS. If these were toys it would be annoying but not a deal breaker, however when it's medication... I have a BIG problem. Sorry Allivet, lose USPS or lose customers....”
