I'm just a private seller with a few Buy It Now listings. I tend to sell one or two items per month, and I currently have fifteen listings up.
I've just received a monthly invoice and they've charged me insertion fees for seven items. Now it's true that I relisted a few things in order to make them look later, and I'm also aware that "good till cancelled" listings technically relist themselves once a month. But I'm sure I'm well within my monthly twenty free listings, plus I'm sure they recently increased the monthly free listings to about a thousand or something, which I clearly never get anywhere near.
I can't even remember the last time I was charged insertion fees until just now.
What have I missed?
