Combined Lots
If a buyer purchase multiple items in the one auction (finishing on the same day) I am always happy to combine the items into a single package for posting. This can result in a significant saving on the postage cost. If you do purchase multiple items please wait for an invoice specifying the combined postage cost before paying.
