Well this is for people in the UK using ebay.co.uk.
When opening a eBay shop i recomend that you open it with ebay.com and NOT ebay.co.uk as ebay.com works in $ for the ebay fees and work out to be alot cheaper then listing items in a ebay.co.uk ebay shop.
For example a listing in ebay.co.uk shop will cost 5p as in ebay.com it will cost $0.05.
0.05 USD = 0.029 GBP total saving of 2.1p yes i know sounds like nothing but listing hundreds of items a week and you will soon find a differance in your ebay fees.
There are many similar advantages just a matter of converting the $ to £ you will find out ebay.com fees are much lower.
Hope this helps.
