sacred that sales periods are calendar events, and most stores close on just three days a year—Christmas Day and the first two days of Chinese New Year. Imagine that: 362 days of unbridled purchasing. Opening hours are equally conducive to whiling your life away browsing the racks: all shops are open until 7 or 8 pm; many don't close their doors until midnight.

It's true that the days when everything in Hong Kong was mind-bogglingly cheap are over. It is still a tax-free port, so you can get some good deals. But it isn't just about the savings. Sharp contrasts and the sheer variety of experiences available make shopping here very different from back home.

You might find a bargain or two elbowing your way through a chaotic open-air market filled with haggling vendors selling designer knockoffs, the air reeking of the chou tofu ("stinky" tofu) bubbling at a nearby food stand. But then you could find a designer number going for half the usual price in a hushed marble-floor mall, the air scented by the designer fragrances of your fellow shoppers. What's more, in Hong Kong the two extremes are often within spitting distance of each other.

Needless to say, thanks to travelers like you running out of space in their suitcases, Hong Kong does a roaring trade in luggage. No need to feel guilty, though—shopping here is practically cultural research. All you're doing is seeing what local life is really like.
