An "expat shop" refers to a store or market that specifically caters to expatriates (expats)—people living outside of their native country. It provides convenient access to familiar brands and products for expatriates living away from their native countries, helping ease their transition to the new location. 

Expat shops sell imported food products, ingredients, and household items that are familiar to the expat community living in that area. For example, an expat shop catering to South African expats might stock boerewors, biltong, rusks, Bakers biscuits, sauces like Mrs. Balls chutney or All Gold tomato sauce, Simba chips, local South African clothing, and cooked food such as bobotie, etc. 

Expat shops specialise in providing products and services that cater to the needs and preferences of expatriates, particularly those who may miss certain items or cultural experiences from their home country. These stores typically stock a wide range of imported goods, including food and beverages, household items, personal care products, clothing, and other specialty items that may be difficult to find in the local area. They make it easier for expats to access products from their home countries that may be difficult to find locally.

Expat shops are commonly found in areas with large expatriate populations, like major cities or towns near corporate offices employing foreign workers.

Expat shops can be physical retail outlets or e-commerce websites. They can also serve as an excellent sales channel for new products from a particular country. Even if the expats are not familiar with the brand, they might consider it "old country." Thus, an expat shop might serve as an interesting co-operative with costs shared among many brands to introduce products in a place where there are many expats.
