Hobsonshoes.co.uk specifies that Coupon Code cannot be stacked together at the same time. Hobsonshoes.co.uk only supports Coupon Code for a single order. You are free to choose, but not multiple discounts. Moreover, the system has set the condition that only one Promo Code can be used, so it is impossible to use Promo Code in combination when paying, and the system will automatically invalidate one of them.
