Looking for opinions, especially from cat owners!

Hey, friends who use or have used the pet-stuff-delivery service Chewy, how has it been for you? Do things arrive on time and in good shape? Have you used their pharmacy to purchase meds? If something goes wrong, do they make it right? I ask because our vet is slowly and inexorably upping the costs of Westley and Hector's fancy health food, and I'm pretty sure doing the same on Hector's two heart meds. Just at a glance on Chewy, I can get their food for cheaper, one of Hector's meds for cheaper, and possibly a generic version of his second med (I may call them and ask about this) for the same lower cost. We are trying to save money as we slip into the holiday season, and this plus not having to schedule around the vet office's varying hours every month would help. Chime in!
