In Denmark we use
www.qxl.dk instead for ebay.
Pretty much the same thing..
I don't sell anything very often, but I find it okay to ad a little to the shipping costs. But shipping costs clearly have to be in the auktion listing! Maybe packing material can be free (I can have perfectly good boxes at work for free), but not always.
Once I bought something the seller actually desided to drive up to me and deliver himself, after I paid him with bank transfer. He desided to use his own car for shipping :lol: I did not complain :-)
BTW, I have 100% positive feedback, and I charge a little extra for shipping. ;-)
