Guam's duty-free status means that name-brand merchandise and other products are often less expensive when compared to the rest of the United States as well as other countries who don't have duty-free status. Most of Guam's hotels on Tumon Bay have a lobby arcade and other specialty gift shops located within walking distance along Pale San Vitores Road. In addition to the luxury designer merchandise, these stores feature Micronesian handicrafts, island clothing, beach wear and other locally made gift items.

The Micronesia Mall in Dededo, the Guam Premier Outlets in Tamuning, K-Mart in Upper Tumon, and the Agana Shopping Center are Guam's largest shopping malls.

Guam's proximity to Asia means that handcrafted and manufactured products from such countries as Japan, Korea, Taiwan, Hong Kong, Bali, Thailand, and the Philippines are available at bargain prices in Guam's retail stores.

Guam's duty free shopping status means that no tariffs are added to many quality name-brand international products. Lower prices on such items as watches, perfumes, leather goods, spirits, and other luxury products can be found.

For shoppers who rise with the sun, Guam's popular flea markets are a special treat. Buyers can find everything from lawn mowers to baby clothes, plants to pets. Hot snacks and beverages are available, and many people enjoy an island-style breakfast of fried rice, eggs and meat while shopping.
