How do I change my postcode setting when I'm looking for somehting local?

[Saltire]

Probably not made that very clear. I typed "pine bookcase" into ebay and a whole list of them came up, then I put the search setting to local/nearest. However it is still showing my old postcode, I ahve changed all my address details , but I don't know how to change the postcode so i can see items in Yorkshire, not Hampshire

Click on the tab down the side which says distance. Then you can put your postcode in nd search that way.

Ok thank you will go and have a look now
