When I use to work there it usually meant that it "should" be on sale/clearance. It all depends on who the dpt. manager is. The stickers are usually placed there by either another manager or the dpt. manager themselves. Then later on the manager should go into the gemini and change the markdown to what they want and/or what it's suppose to be from their list of markdowns. l
But it is a good bet that its on sale or should be on sale. If its not marked down then wait because most of the time the associates won't know when the price is going down, if it hasn't already. It all depends on whether the dpt. manager wants to mark it down (that's if the markdown is not a home office markdown, because sometimes they do it themselves). Also, most stores have their own sticker meanings.
