Como deixar uma li de uma lista sempre em baixo?

galera tenho um lista de promoções e fiz essa lista em <ul> <li> veja em baixo:

/applications/core/interface/imageproxy/imageproxy.php?img=http://4.bp.blogspot.com/-ZKICIxxMhp4/UCKZXp6lJ_I/AAAAAAAAAMM/WfbcY-EmRwA/s1600/img.png&key=3219985bc9c99b40496591b7bffce71b85f7b05cf1e5382e8dc75255f6890579" alt="img.png" />

só que eu queria, que a parte da li aonde tem o desenho veja a oferta em verde sempre fique colado em baixo veja um exemplo:
