did you know you can set off the alarm with a dvd? i took my granddaughter to the mall and had her "elmo" dvd in the diaper bag. i couldn't figure out why i kept setting off alarms when i hadn't even bought anything. finally, a clerk asked me if i had a dvd with me and sure enough, that was what was setting off alarms. she ran it over her pad that neutralizes it and we were off and running.
