If you want to save money on electronics, Amazon is a great place to shop. But you'll want to avoid overspending on extended warranties or buying no-name electronics from third-party sellers. Those are some surefire ways to overspend. Here are a few more mistakes to avoid.

Dottie from Boston, Massachusetts, loves to go on long walks with her partner. Unfortunately, that means she sometimes loses her phone while enjoying the scenery. She asked me for the best app for tracking down her lost Android.

I suggested Google Find My Device. By installing this app on a trusted person’s phone, you can use Google Maps to find your way back to your lost Android. You can even secure the device to make sure strangers aren’t sneaking through your secrets.

Even better, you can add a message for anyone who finds your phone, letting them know where to find you. In a worst-case scenario, you can even erase the device. (Hopefully, you’ll find it before you start considering that, though.)

Download the app here for Android.

I didn't forget about you, iPhone owners. Here's how to find your lost device.

It wasn't that long ago that online sports betting was illegal throughout the U.S. But over the last few years, it's become legal in many states and people can't get enough. In many places, you can now bet on virtually any game at any time, right on your phone. So how did we go from no online sports betting to these gambling companies airing dozens of ads every game?
