Some items which have “Buy now” button have “Time Left”. There are several units available (e.g. : 5 available). What does the time left mean?
well after the time left is over the item is no longer available for purchase, but the ebayer can resell the item later by republishing.
This is correct – it simply refers to the amount of time the item will be left on sale for. Once the item passes this date, it will need to be re-listed.
The item has a fixed price and is not up for auction.
