When you order multiple different products you will be charged postage & packaging cost to send out each product individually. In cases where some items are pre-orders and others are available this is a logical solution. However if multiple products are readily available this can lead to excessive p&p cost. We will always contact you as purchaser what you prefer. And we will reimburse you the excess p&p cost, of course!
This issue is caused by the limitations of the software platform we are using. We have asked them to correct this issue so hopefully this will be sorted in the near future! Our apologies for the inconvenience.
