i ordered something ( was going to be a wee stocking filler gift for kids ) back in early november from hong kong thinking it would arrive before xmas , well it didnt so at beginning of jan i opened a case and seller offered me refund which i got ( was only £6 )
anyways ,,,, the postie has just arrived with item ! checked the postage stamp and was dated on 26.11.10 !

what do i do , let the seller know ? , refund the money back ti them ? keep quiet ?

I would let the seller know that it has arrived and offer to send the money again.
That's the honest thing to do.

I would let them know as that's what I would hope someone would do if I was the seller x
