These are 2 one-off codes, giving you 10% off sitewide on eBay valid on everything over £25 and max up to £50.
I kept it for a week but there's nothing I need at the moment. And I don't know the code expiry dates. I just tried and it's working when posted this discussion.
Please DM me If you are after one. It's of good use if you are buying from Currys or Argos from their eBay store.
Have a great day.
