From 27-28 April 2013, private sellers that list up to 100 auction-style listings at a starting price of £1.00 or more in an eligible category on eBay.co.uk, won’t pay an insertion fee. Additional listing fees, such as those for adding extra photos, still apply.
To be eligible for this promotion, you must:

• List your item(s) with one of the following:
  •  eBay Mobile applications
  • Our new Quick Listing Tool
  • The Quick Sell or Advanced Sell (Sell Your Item) forms

Items listed using professional tools, such as Turbo Lister and Selling Manager Pro, are excluded.

• Meet eBay’s minimum seller performance standards. Check your Seller Dashboard to find out if your account is eligible.
