The beginning and end of summer are marked by two long weekends: Memorial Day and Labor Day. Memorial Day serves as a reminder to finally pack up all your winter stuff and throw it into storage, and Labor Day does the same for all our summer goodies. Both those weekends also rival Black Friday as the best times to snag just about anything you want on sale.

Sure, the idea of buying even more summer stuff might not exactly be appealing right now. Forget that: You have a solid month of sandals and shorts left, so milk it while you can. You'll miss the heat by December.
