Postage for the first packet of seeds is a flat £0.65. P&P for any additional packets is completely FREE. For multiple purchases, please purchase all the seeds required before proceeding to checkout. During checkout you will be asked to combine your purchases and as a result the final postage should remain at £0.65 with recorded delivery an optional extra. If for any reason you encounter a problem, please e-mail and I will send a combined invoice to you. My aim is to post every order within one working day and you should receive your seeds very quickly. PLEASE NOTE: the postage discount only applies to purchases which were combined and paid for in one payment
