Questionable Product Placement in HIMYM?

In a 2007 episode of "How I Met Your Mother" called "Stuff", two main characters, Robin and Ted, are sitting in Robin's apartment. On the table behind their couch I could clearly see the new movie "Friends With Benefits" starring Justin Timberlake and Mila Kunis standing there. This movie has not yet come out in theaters (it doesn't come out until July 2011) and also did not begin filming until 2010. How could this be possible? Anyone have any answers?
