Happy to combine shipping, it's not quite as easy to do this on eBay these days! so below are three ways you can get your shipping combined.  These methods apply to UK and overseas orders.
1 - Check out and I will refund excess before shipping.
2 - Check out first item then send offers minus 75% of shipping cost (only possible if the cost of the item is greater than the reduction).
3 - If you want to order lots - more than 10 items - send me a list, I can cancel the current listings and put up one job lot listing with combined shipping that I'll only sell to you.
I only use Royal Mail and I now only use tracked services (Royal Tracked 48hr is the standard shipping method).
