I buy medication from Fosters and Smith for my dog that has a pancreatic enzyme deficiency. That company is now owned by Petco. I recently placed my order and selected standard shipping 4-5 business days. After 4-5 business days I didn't receive the medication. After checking their website, it said I wouldn't receive it for another WEEK! We've run out of the medication and now my dog is getting sick. My vet is at Banfield Veterinary Hospital located within Petco. How much easier could this be?! The Petco website customer representative wasn't willing to take any measures beyond taking a 2nd order and charging me for expedited shipment. Not willing to contact the vet directly to speed up approval and shipping of the medication. Also, not willing to credit me for extra shipping costs. The 2nd order is only going to arrive a day earlier than the original order. But with my dog getting sick I'll take that extra day at the very least. I don't have an issue with Banfield or my vet - they are great! I would highly encourage people to find another supplier for your pets medication! If you are concerned about reliable service, shipping delivery as promised and your pet's health avoid Fosters & Smith/ Petco for your beloved pet's medication!
