Just in case anyone is interested, I just ordered Jess' Prascend online with Viovet, I think there might be slightly cheaper out there but I have used viovet a lot and trust them. I put it on an auto delivery which gets an extra 10% off and saves me remembering to order it each month and my normal monthly bill of £38.65 will now be £29.43 as its free delivery, yes, I have to pay the vets £18 script charge but it still works out way cheaper It was easy to just upload a scanned copy of the script straight to their website too and they processed the whole lot in under an hour
