A "bump" is when a thread goes up to the top of the list on a page, so oftentimes sellers will "bump" there sale thread which makes it more visible at the top of the page....Any reply to a thread has the effect of "bumping" a thread. There is a certain etiquette involved where you are not supposed to be constanly bumping your thread since that is impolite to other sellers, i think you can do it once a day though
