It looks like they're trying to bring more European and British buyers into Etsy, since it's quite big over in the US already.
They're asking sellers to share this code, which gives you £/€ 5 off a purchase of £/€ 10 or more, and the sellers don't lose out! Yaaay!
Please note that if you have an account, I think you need to make another one to use this code, I believe it is only for new customers.
Here is the code,

It can be used all over Etsy, but if you're interested you can check out my shop here -

Just thought I'd give everyone a heads up! I would have loved this code a few weeks ago when I purchased something..
