Maybe it is all the tracking costs and such that sellers are supposed to have nowadays, to cover themselves.

I know not all sellers use it but they are taking a risk if they don't.

I used to sell years ago, but back then we just put things in a bag and off it went. Buyers paid extra for insurance if they wanted it.

And buyers could give negative feedback too.

Things have changed on ebay and some sellers are covering their backs I think. It is probably wise to. In fact, I wonder how viable it is now to sell low priced items because tracking would add more to the cost than the whole item is worth at times.
