Have never bought anything from them but I get my Cortaflex from these people, good prices and very quick delivery usually next day. Might be useful for next time. http://www.cortaflexsupplements.co.uk/
I ordered some stuff from them on recomendation from my farrier. (via ebay) I got a message saying they were away until 14th August so would process orders after that.
Thanks so much palomino_pony! I've been fretting for the last week as I want my hoss to go on it asap, hopefully won't be too long then! They could've sent me a message too!! I've already sent two emails to them asking what's happened to it....
