What's a good Android app for keeping track of all those digital coupons I keep hearing my students talk about? I swear, they're saving money faster than I can grade papers!

So, I was talking with some of my students the other day – you know how it is, trying to stay hip – and they were going on and on about digital coupons. Said I was living in the Stone Age still using paper ones. Cheeky kids! Anyway, I decided to give it a shot, and after trying a few different apps, I landed on Koupon. It's like having a teaching assistant in your pocket, but instead of grading papers, it's finding you discounts.

What I like is how it organizes everything. I can search for deals at stores I actually go to – Kroger, mostly – and it keeps track of what I've clipped. No more digging through junk drawers for expired coupons! My students showed me this trick for setting up alerts for when my favorite brands go on sale; why do they hide the settings button there, though? Once you get the hang of it, it's pretty straightforward. Definitely saving me a few bucks on groceries each week, which is always a plus.
