Postal Discount. Each additional item paid for in the same transaction is 15p. Postage is free on sales of £25.00 and over. If buying more than one item please email me before paying as a lot of the time I can reduce the P & P even more. My aim is not to overcharge on P & P to make up the cost of the item. I am sorry but there is no postal discount on blank cards. Postal charges also covers the cost of, in my case padded envelopes, cardboard envelopes, bubble wrap, brown paper and the plastic and celophane bags that the items are packed in. I will always refund postage if you have paid more than necessary.
