Thanks for the advice.  

I never thought to check as I thought "relist for free" means exactly that.  I always only  list with the basic free stuff - no subtitles or extra photos etc.  So you'd think it should be free...

So what is the "limit"? I've been a member for years and it's the first time I hear there is a limit?... I find ebay very difficult to find the "rules" - it's very easy to list stuff and buy stuff, but the adminitrative stuff and rules can only be found through a maze of links and clicks.  It should be upfront and clear so it's easy to view and understand.  You've obviously been a member for many moons and even you don't know why it sometimes charge a fee and sometimes are free and you have to juggle your way around it...  It should be clear and consistent.

Thanks for taking the time to answer.  We live in a world where you need to check your change, what you're charged and all the sneaky other stuff all the time.  Nothing is as it seems and nothing is for free, even when it says it is...  I'll now check every single thing with a magnifying glass.  

Very expensive lesson learnt!  Not sure I want to use ebay anymore - they've changed it in so many ways to benefit only ebay.
