Buyer wants to send prepaid postage label

[notcitrus]

Buyer for £5 item wants to "settle the item price by paypal & post you a prepaid postage label for the £6.99. I will need your address."

Is this some kind of scam? I can't think of how - if the label isn't recognised by the PO I don't send. Sounds like hassle though.
Anyone heard of this before?

I wouldn't. Could be a scam. You send it yourself:

Not heard of this except sometimes when a buyer is sending something back weird and the seller funds the postage up front [confused}.

It isn't a scam. But still, advise that the postage is as it is on the listing and the total price is the item price plus the postage by PayPal advise you will not accept the postage label.

Further advise that the postage costs also includes packing materials.

Thanks people - I said I needed payment for item including p+p before packing and going to PO, via Paypal or cheque/PO, as stated in my listing.

Will see what happens... I aim to charge about 20-50p more than postage cost to cover sellotape and hassle factor.

Posting always seems to be such a hassle-so much so that I now put free postage and put the price up accordingly-it has the disadvantage of giving higher starting fees, but I find it worth it.
