Modular LEGO Store #910009 worth

Based on the catalog information you have on screen, the Modular LEGO Store #910009 is listed with a used value of $445. Since the second item, "LEGO Modular LEGO Store (910009-1) (BrickLink Designer Program)," is unpriced in the catalog, I cannot provide a specific value for it. For the #910009 set, the typical value is driven by its status as a BrickLink Designer Program set, and you should check the live eBay listings shown on your screen to compare current asking prices against that $445 sold value.
