Hello there, I'm having this same problem. I have a load of stuff I want
to sell. I will be away travellig for afew months and have the time now
to put the listings on now as drafts to get ahead of myself so I might
take advantage of the free listing...
'You can also save a draft of your listing and go back to finish it
later. There are no limits to how many drafts you can have in Seller
Hub, although they expire after 45 days.'
