- Be prepared for when a big sale does come. There are certain sales you know will happen: Shopbop's annual one, the doozy at Net-a-Porter.com, and the occasional fabulous few days at Kate Spade. If you're already familiar with the offerings, you'll be able to buzz through, adding stuff to your cart and getting to checkout before the non-everyday shoppers have even figured out what they're interested in.
- You'll always get your size. Certain pieces are so special they'll never go on sale, and, chances are, they were made in a relatively small run, so if your size is gone, it's gone. Keep your eyes open always and you're less likely to come back to a bookmarked item weeks later and find out your size sold out a week ago.
