Thank you. Finally managed to work my way through this maze. Question to Trademe: Why change the original way of setting email reminders, which worked perfectly fine and was uncomplicated. If it ain't broke... 

Yep agree with David. One now has to constantly check and reset the setting. Very annoying. 

Where is the Email notifications page please?  

I read Callum's instructions. However, there is no option visible to me that says "Apply these settings to items currently on my Watchlist". There is only "Always use this option". I tick my time preference, I then tick, "Always use this option". But when I leave the page, the my reminder setting goes back to "None". 

Same problem here. I do not have the option "Apply these settings to items currently on my Watchlist". There is only the option ""Always use this option". I tick it, plus my time preference. When I leave the page, the setting goes back to None".
