Playing chess with pigeons
I buy my wormers online-except for Quarrie because Drontal makes him sick. So cats, dog and horse wormers (and flea preps for cats) I save money on.
I get them from the vets as I thought they were better. TBH I will probably still get them from there, I support local business generally and I only have three dogs to worm so it is not exorbitant.
