Sods law isn't it.
Typical, i ordered the ones from Vetuk Monday (annoyed)
Petshop.co.uk are doing these at £9.09 currently 3 for 2. You have to select subscription service, but you can cancel at any point by simply logging into your online account. It's £1.99 delivery, but free for orders over £19.99 so I just added a couple of drontal worming tablets to get free delivery. That's 1 years flee treatments and 6 months worming treatments for £20.34.
Used to do this and just store it in a small sterilised bottle.
Thank you will order now
