Im having a little bit of difficulty with an ebay purchase. The seller and I seem to be getting tangled up in politeness and I'm not sure what is fair 
I bought a skirt, that was described as being perfect, brand new etc. When it arrived, it has clearly been made wrong - it is a kilt style skirt and the buckles are in the wrong place. However I think that with a bit of effort I can detach them and resew them correctly.
I contacted the seller who offered a full refund (and no return).
I replied saying that I thought that was excessive (skirt inc postage was 19.50), and that perhaps a small refund would be better, as I do think it can be fixed.
She hasnow very kindly got back to me saying I can have whatever refund I think is suitable, or if I like she has a matching cardigan that she can send me in place of a refund. I really like the sound of the cardigan, but not sure if that is fair (Im slightly tempted to ask for the cardigan and offer her some money towards it, but thats making things even more complicated)
Can someone please talk some sense into me and tell me what seems fair?
