The orange pins are SASSIE mystery shops.  These shops are done using different software, and they are mostly assigned by schedulers, not self-assigned.

If you see a SASSIE shop on the Presto Map and you want to apply for it, click the pin for the shop details, then click the Apply button in the details:

This opens the mystery shopping company's login page in a new tab or window.  Log in here to apply for the shop.   If you don't already have an account on that mystery shopping company's system, you can create one.  You should address any questions about the shop, shop assignment, or any other shop details to the scheduler on that system, whose contact information should be available on the shop listing on SASSIE.

To apply for a SASSIE shop, you must log on to the mystery shopping company's SASSIE system, not on the Presto map.
