On the top of my pages, it says Super Sunday, list as many items for $0 insertion fees and pay only $1 when an item sells promo but when I click on it, it says invitation only.
09:22:44 UTC justkidzbiz
Yet it is on the top of all my pages
09:23:46 UTC justkidzbiz
Is there any way to upload a screen image here so you can see what I mean?
09:26:00 UTC justkidzbiz
I had no trouble last week with the same Super Sunday offer but this week it says invite only but is showing at the top of the page in My Summary
