A similar thing happens to me too. I load listings via a computer, using the desktop site and set the closing time. Sometimes to a few minutes past an hour. If I need to edit the listing, I do this on my ph in the app and I can't keep the closing time to the same as the original. And it won't let me set it to a few minutes past the hour.

Shipping is not postage alone; it can also include the cost of items needed to safely & securely ship the item. Ie good quality bubble wrap/new cardboard. These things don't grow on trees, so it's fair enough to expect this is passed on.  And if the seller lives out of town and you've asked them to run into town to post it to you, why shouldn't you contribute to that cost?  Was it a pick up only item?  Did you get the item for next to nothing? Does it need wrapping to protect it on its journey?    $10 sounds excessive, but you don't know what hoops the seller has to jump through to ship it ...

With the new shipping template, I couldn't work out how you add an RD option. Is this not possible anymore?  I'm continuing to use the template I have in My Products, but I see I'm being disadvantaged by not using the new template, even though I'm not a professional seller. I'm helping my family find new homes for their bits & pieces!
