Well I found the generic at Sigma-Aldrich in the US & and DOMVET, a Canadian site. The former is available as 500 gms as opposed to a lb of sulmet, but perhaps it's not too bad a price after all. Shipping from CA to the USA is the same as from Milwaukee but the overall price is cheaper in the US probably because of the rate exchg.
