I don't think it's hard to do it. They are just mean.

I only have a handful listings to do and all multiple quantity items. I will pay a dollar or two to avoid extra work in a month time.

But I think it's good for a big volume sellers who can list 1,000 items in 4 days in one category. But maybe those sellers don't care much about saving $200 considering they have to re-list 1,000 items in a months time.
