Firstly, please check that the promotion code is still valid and that you are typing in the correct code.
Due to the number of discount codes Seedsman offers, you are only able to use one discount at a time.
There are often rules to promotions, so please make sure you have followed the requirements outlined.
If you still find that you are having trouble applying a promo code to your order, contact us and we will look into this for you.
Products on sale
Products marked as on sale do not get any further discounts from coupon/promo codes.
