Two new SABRE alarms - $10

Two new, still-in-package SABRE Home Series alarms: one Motion Sensing alarm and one Shed & Garage alarm.
For cash sale--basically get two alarms for the price of one.
Got these for my garage and my shed, but ended up not needing them.
I am unable to phone or text (no service) and internet is limited to the library WiFi--I can try to check email every few days.
I respond to all polite messages, so if a day or two has passed without a reply please check your junk folder/spam filter.
Meeting location is in south Saint Louis city at my home near the intersection of Morganford and Humphrey.
I am available most days during daylight hours for pickup as long as we arrange it in advance with a specific day and time.
