You guys, THIS IS THE BIG ONE. The Net-a-Porter Semiannual Sale is always my favorite online luxury sale of the year, and arguably the spot for the best deals on designer handbags (and designer everything else) that you’ll find on the Internet. This year, the sale includes five pages of discounted bags, from Marc by Marc Jacobs and Tory Burch to Alexander McQueen and Proenza Schouler. Hurry – luxury shoppers anticipate these markdowns all season, and the most covetable handbags can disappear in an instant. Also, watch out for our sale picks, coming this afternoon!
