Q: how to find cheaper pet medicine

Hey guys,
So…this is probably going to sound insensitive, and I hate for anyone to think I’m skimping on my dog’s care, but it’s because I love and want to keep Annie that I have to ask, because I really need to cut back: has anyone on here found any good places to get cheaper pet medicine? I’m spending a lot on her healthcare and I think there must be somebody out there who can help me keep her healthy for less than I’m spending now…
Thanks a lot in advance for your help
