I have played around with the priorities of the discounts but I think it might have been working already. Essentially the discount applies to the price excluding VAT. If there is something that you can put with the crank it should just about tip it into the bigger discount. Rest assured the Sugino cranks are much cheaper than they would be if we had to re-order - we managed to get those in before the currency tanked with EU referendum last year.
