Attention Shopaholics! Throw a collapsible duffel or large tote in your luggage.

Will you buy out the store? Be prepared. Store an empty bag inside your medium-size checked bag rather than bringing a huge suitcase to accommodate future purchases—you can use it as a day pack in the meantime. Fodorites love le Sport Sac, Baggalini, and Longchamp’s Le Pliage.
