For sale: Prinovox Dog flea/worm treatment. Spot on. 11 doses.

I've got 11 months worth of Prinovox for dogs between 10-25kg. It's a monthly spot on treatment for fleas, mites and worms. Expires 2023 and bought from Hills. 

Paid about £140 for it but moved my dog onto a tablet version as it was easier to get him to eat something than wrestle him for the spot on. 

Looking for £50 to recoup some of the costs.
