In a general search as a guest in a particular market, some listings have this little "ticket" on their prices in the map (see small arrows on the map). Then, when you select a listing with the "ticket" (large arrow) it pertains to the listing on the left (arrows at the price and the "new lower price" notation). The "regular" prices is crossed out and a less-expensive alternative is presented.
These listings are being presented to guests as being some sort of "deal" with a "new lower price" on the listing itself. How did these listings get that distinction?
