We used to pay £13 for 25 ltr it’s now £22 but did go up to £38 at one point the supplier we use is only allowed to order 20 drums at a time from who ever supplies him it’s a small farm shop , we now pre book an order and buy all 20 at a time in advance , apparently there is a world shortage of hypo as it’s made in the Ukrainian so I was told don’t know if that’s true or not ?.
