I googled 'battles' (wholesalers) and 'caprivite', got the ref number for the size I wanted then put my postcode in and it gave a list of local outlets, (sounds complicated but was easy) I actually get a horsey shop (Moody Mares, Mytholmroyd) to order it for me along with their delivery, saves postage and I know the delivery day. local Agrimerchants can't be bothered.
