Add Gibraltar Trade Center to the casualty list of real-person retailing falling victim to to the online sales revolution.

The Taylor site closed in 2014, now the Mt. Clemens site will close on August 27. The site has already been sold.

President and CEO Bob Koester says "the impact of online sales on small brick and mortar businesses is substantial" and that "declining revenue and sales are forecast to continue to accelerate in the years to come."

The company says the popular Gibraltar Gun and Knife Shows will continue to operate.
