Thanks so much for getting in touch. As we send different seeds every month, we calculate the monthly cost and discount as an average. Meaning that overall during the year you will have saved money. It may be that the odd month the total costs of the seeds are cheaper and other months much more expensive (chillies and tomatoes for example cost a lot more). Rest assured, you are benefitting. The other advantage of the subscription is that we do the thinking for you and send you the right seeds at the right time to sow them.Thank you for your continued support and custom - it's much appreciated for our small business.
