Amazon has the Sigma 18-200 for $319 shipped (only 3 left @8:10PST), plus 55 free Shutterfly prints.

B&H also has it for $319 without the free prints, if for some reason you don't like Amazon or if they go OOS.

My wife loves this lens, 18-200 is great for walk-around shooting, it gives you good range from wide angle to decent zoom. It feels solid, and has a nice grippy texture. It's almost always on the D-reb, except when she wants to shoot portraits, in which case she goes with the 50mm f/1.8 ($94.83 shipped), which is also fantastic, and they're both EF lenses.

IS version is available at 47th St. Photo for $364.95, possibly +shipping, or $399.92 shipped at Amazon.
