hi,my dog also has epilepsy and it costs me about £28 for 18days of epiphen and she also has kbr meds too which is about £20 for month supply.i havent thought about trying online.....might be worth having a look..thats a shame you havent got your dog insured as i no how much it can cost!!!! we were lucky to have our dog insured as soon as we got her,otherwise its a costly time..let me no how you get on if try online..marie
