A "pop shop" is a small retail store that operates temporarily in a specific location or for a limited time. Some synonyms for "pop shop" include "temporary shop," "pop-up store," and "temporary retail outlet." These types of shops have become increasingly popular in recent years because of their flexibility, low overhead costs, and ability to create a sense of exclusivity and urgency amongst customers. Other similar terms could include "flash store," "pop-up boutique," "temporary outlet," or "guerrilla store." No matter what you call it, the pop shop concept is a great way for retailers to test out new markets and build buzz around their brand.
