When you go near a place, send a reminder
I use this a couple of ways. 1. When I go near Joann I am reminded to get batteries because they almost always have a 40-50% OFF coupon and you can use coupons on batteries too! 2. When I go near the museum or the nature park, I'm reminded that they're closed on Mondays (I showed up on Mondays a lot before I had IFTTT).
