Members of the Founders' Club are indeed entitled to 10% off online only. This discount is not automatic however and you will need to enter a code to claim the discount.
To be reminded of the code, please contact firstname.lastname@example.org.
Please note that, if you live locally, you can use the 10% online discount and choose Click and Collect, meaning that you can collect your order from the distillery site and not pay P&P. Founders discounts are not applicable with any other offer.
