there was a long debate on the boards just recently about this:

 

http://community.ebay.com.au/t5/Selling/eBay-Satchel-lodging-over-counter-lt-gt-Seller-Protection/m-...

 

and I don't think anyone came to a firm conclusion!

 

Personally, I use the ebay satchels - get a receipt at the counter of the PO - I don't pay extra for signature

 

the ebay satchels and postage labels are cheaper than the prepaid satchels over the counter and cheaper than click and send.

 

Ps:   If I were you I would amend the ski boots listing, you are not allowed to say FREE POSTAGE and then put postage in the listing.
