Even when designer gear goes on sale, it's still not cheap. 80% off $500 is still $100. So, when you see clothing you know goes for beaucoup bucks suddenly drop to Old Navy-like prices, chances are something's up. Also, websites generally are more expensive than in-store sales, for the express purpose that the latter serves to get unwanted things out of brick-and-mortar spaces to make room for newer stuff. Take that into account before you pull that virtual trigger.
