got this free relisting thing worked out now.

I ticked the box for the free 3 relistings, and as my card did not sell it relisted.i took notice of how many free listings I had left, and the free relisting did not take another one off. stayed at the 96.

so if you tick the box on your free 40 or 100 listings, if not sold they will relist without using any more up.

you will only be charged  the listing fee, if you have used up all your monthly freebies, and only works on auctions.

you can also go and revise your items to tick the box, if you didn't do it before, if you were unsure like me.

happy selling.
