When buying clothing on ebay especially from abroad make sure you read the small print- sizing, quality and the actual it's can have hidden surprises.... I learned the hard way by bidding only having looked at the photo and the size stated in the title! Turns out a large I china is around a size 12 not a 16!!
also check delivery times ...a top needed for 2 weeks time is unlikely to arrive in time.
don't be swayed into not giving bad feedback for a refund if you want to prevent other people falling victim to shoddy items.
Or even items not received in the post.
If its a private seller then make sure you want what you are bidding for as its very disappointing to get a 'no show'. As a seller yourself make sure you are completely honest about the item.
I have found the maximum amount of photographs gives an honest and realistic idea of the item and if you can remember how much you paid for it pop it in the description!
Also state if you have a smoke free, pet free home as people with allergies like to know this info.
