Aer Lingus Gold Circle Points are not that valuable in and of themselves. There redemption level for flights is quite high and you still have to pay taxes and charges. Having said that they are useful if you need to buy back your status, and having status is quite valuable if you fly out of Dublin regularly. However this offer came to me by email recently and I thought it would be a good idea to try it out.
It offers gift cards at upmarket retailer Brown Thomas in exchange for points. 500 gets you €25, 1000 gets you €50 etc. As I had some points expiring an decided to use it. You have to email your details to firstname.lastname@example.org stating how much you would like and your GC number. I got an email back later that day to say the card is on its way. A good use of some surplus points, perhaps for spending on christmas?
