what happens when my time is up on an item and no one buys it does it automatically come off and then do i have to repost it back on?
The listing will end at the end of the duration of the auction.
You would need to hit the relist button within the listing to put it back on. If it sells the second time around, you may get a listing fee credit
Details about relisting items here:
I would also suggest you make more use of the space available in the Title e.g. add size, colour, make etc.
