50 Tab pack of Virkon is £11.99 plus £2.50 p&p
I've found it quite easy to get hold of, most of the equestrian shops round me sell it in various packs (£1.50 for a 5l sachet in Robinsons at Haydock when I was last in), agricultural suppliers usually stock it too. I'm told by a farmer the cheaper "pet" branded version is the same as the DEFRA approved stuff but with different legal blurb.
Cheers,
Stuart
