"generate a shipping label bearing that address and then have it sit around?"
I think you misunderstood the post.
Femme is referring to postage stamps which can be used for years to come to pay for postage. Canadians can use Canadian postage stamps available from Canada Post and can also use postage stamps made available in Canada years or decade ago, including those issued by Newfoundland prior to joining the Canadian Confederation in 1949.
There is a specific clause in the act allowing Newfoundland stamps to be used for Canadian postage.
I do that from time to time - with old $0.05 or $0.07 Newfoundland stamps - to "spice up" my envelopes.
You have to take the comment in the context of the question you had asked which suggested that a seller needed a shipping label produced by eBay/PayPal.
Many sellers, myself included, never ever used eBay/PayPal shipping labels.
I print the shipping label using standard Avery labels and affix the appropriate amount of postage stamps on envelopes or parcels.
It is way cheaper than using PayPal so-called "discount" postage for some postal services as I (like "femme") typically purchased postage stamps at 30% to 40% discount from face value.
And the same applies to American sellers who can easily purchase American stamps at deep discounts.
I agree with you the seller may have been confused as to where to ship but that is another story.
