Designer stilettos and leather boots can drain a bank account quickly. But not if you shop at Samantha Castilla Shoe Boutique. Each week, the Cherry Creek North shop knocks 40 percent off the price of select kicks for its "Shoe of the Week" program. This means that every seven days a girl can score a different pair of shoes (think eggplant mid-calf boots by Sigerson Morrison or even Christian Lacroix's peep-toe pumps) for usually hundreds of dollars less than the ticket price.
