A loading-dock signaling system includes an internal signal light, an external signal light and a wheel chock having a base and a handle extending from the base. A chock signal light is positioned on the handle. The internal signal light, the external signal light and the chock signal light are in signal communication with one another to provide at least a plurality of illuminated indicia to an exterior dock area and an interior dock area. The exterior dock area and the interior dock area are separated by a dock door.

The disclosed systems and methods may request a merchant identifier associated with a merchant from a third party, receive the merchant identifier, retrieve or receive a first uniform resource locator (URL) associated with the merchant, and store the merchant identifier and the first URL in a database. In response to a web browser extension detecting that a user is preparing to make an online purchase associated with the merchant, the system may receive an age request for an age of the merchant from a user device and identify the merchant identifier in the database based on a second URL included in the age request. The system may then request the age of the merchant from the database based on the merchant identifier, receive the age of the merchant from the third party, and transmit the age of the merchant to the user device for display.
