I combine postage regardless of what eBay says.

Please purchase all the items required (press buy it now confirm and pay button) but please,  do NOT go to PayPal and pay. 

Please do NOT do a checkout saying payment by other method as eBay will not allow me to change the postage if you do so..

 Please leave and I will adjust the postage.

 Yes, you can confirm purchase without paying as I do not require instant payment. 

Please note:

If you choose the Tracked Signed option you will get the correct postage without waiting for me to combine.

All parcels with value of   GBP20 and over MUST be tracked both UK and worldwide as per eBay rules.
