My Greyhound needs Deramaxx and my Komondor needs Rimadyl. The Deramaxx used to be affordable in the 100mg tablets, but they've stopped making them. My vet recommended I try to find the meds online because it would, for sure, be cheaper. I've ordered through 1800PetMeds. I'm awaiting my first shipment, but the cost of the Rimadyl was almost half, and the Deramaxx was at least .25 less per pill, which is huge, since the 25mg pills (all they're manufacturing now) cost much more than the 100mg pills did, dose per dose. I haven't received my first shipment yet, so can't say how well all that's working, but the website itself was very easy to use. I'll keep you posted, but it may be worth checking out in the meantime.
