I setup an autoship with Chewy.com. First autoship was seamless. Second one never arrived. My pet ran out of meds. I had to call. The shipment was "stuck" because they forgot to list the vets approval on the order. It is very concerning because my vet approved the prior 2 orders and they admitted that they had the prescription on file. Someone should have noticed that the order had not gone out and was more than a week past the ship date. If I hadn't called, their system wouldnt have caught the mistake. I will be looking for a new online pet supplier as my pet can't afford to miss meds as she has due to this issue.
