Hi signsintime,
Yes, there is. To create a shipping & payment details statement, you can go to Auctiva -> Listings(tab), then click the "Shipping & Payment Details" link.
Then, when you're creating your listing, you can select your shipping & payment details from the "Select Ship/Pay details" pull down menu on the lister page...it's just to the right of the counter pull down menu. Once you have selected a shipping & payment details from that pull down menu, the infomation contained within it will be displayed where your [PAY_SHIP_DETAILS] tag is on the template.
I hope this helps=)
