Item I sold not as described, happy to refund but do I refund postage too?

[FadBook]

As above really. Have now received item back which was a phone (thought it was unlocked, it wasn't, buyer wanted £25 to unlock it, I said no, send it back and I'll refund you item cost) - just about to do the transaction refund and don't know whether to refund postage of an additional £8.49?

It's been very amicable up to now and we'd both already left each other positive feedback (prior to him realising the phone wasn't unlocked).

Am I obliged to refund postage or is it a 'gesture of goodwill' type thing?

Refund the postage

Yes refund postage

Too true, thanks.

Have refunded it all. Don't know why I found the question so difficult to answer I was just thinking about 'normal' refunds and some places don't pay the postage etc, but I'm forgetting that I was in the wrong with the listing
