thanks again for your advice. I now find that I am registered as a Business seller and cannot get free re-lists, so that explains why I couldn't find the auto re-list checkbox.

When I was looking at my monthly selling limits, April selling activity, they advised me that 'you can list 66 items'. This is misleading for a beginner. When I scrolled down to 'promotional offers' I saw that yep, I had indeed posted 40 items. so that explains the $1.50 insertion fees.

Just taking baby steps, but I'm a stranger in a strange land!

This discussion page is very helpful. Many thanks
