Wow...I know there's bound to be variation but £72 seems extortionate! That's the most expensive I've heard of by some significant margin - I think £57 was the most expensive I'd heard before now. I would definitely query that with them, that just seems really OTT if it really is per bunny (if it's filavac, it comes in a pack of 5 but they are individual vials - I wonder if they've based the price on a pack purchase). In my signature I think there's a link to our map which plots vets we know about who have the vaccine - it might be worth you looking and seeing if anyone else nearby has it and asking them how much they're charging, either to see if your normal vet will drop the price or to consider whether to go somewhere else for it. I don't normally advocate chopping and changing vets but frankly for that price I think I would!
