We are happy to deliver your purchase in one delivery. If you buy the products through the 'buy it now' button, please remember to either add the purchase yourself or have us combine it into one before making the payment. Alternatively, you can also buy the desired products via the eBay shopping cart. Single payment via Paypal can not be subsequently combined due to the specifications Paypal and must be sent as separate packages. A postage refund is then no longer possible.
