Yes springy, if it's too long, many buyers won't read it.

I am guessing that listing you saw, the seller uses a courier and needs a phone number. Some couriers won't pick up unless there is a phone number for delivery contact.

You have reminded me to also put that it's postage and handling costs in my new terms. Thanks.

But I have found the buyers that have complained about postage being more than paid are usually the parcels that have the printed cost rather than stamps
