Seeing as it looks like sellers need to "send" the buyer a return label once a dispute is started and the buyer has

to return the item.

So how is that label accessed?

I presume they don't send a physical label so how does the seller pay for and send the label?

These type of returns are starting to appear on the boards but I haven't come accross a seller actually sending a

label,(so I'm just interested in how it works).
