I got a pair of converse from Ebay once.. They were buy-it-now (brand new) for around a fiver so obviously I was skeptical but I saw the user had good feedback and bought them.
To my surprise they turned up and looked just like any other converse trainer I had ever seen!
Just be careful because after this I foolishly felt very trusting of Ebay and bought a pair of vans (without reading the feedback first..) and basically got scammed by some chinese user -_-
