Pop-up locations provide an opportunity for e-commerce merchants to interact with customers in a way that is unusual for them. A pop-up shop can be an extra branding tool for retailers that don’t normally have a physical store presence, enabling fans and potential customers to interact with the brand in a physical space and actually handle merchandise. A pop-up shop also gives merchants an opportunity to communicate in person with their customers and create a deeper connection.

Merchants use pop-up spaces as a strategic means of clearing out stock or excess inventory or promoting a new product. Pop-up shops also drive sales and act as additional sources of revenue.
