How Millennials are saving money these days

I still have a ways to go before I become debt free, but I love when I hear of new ways people are learning to save a buck or two or three.
My sister recently told me about an application you can download to your browser to search for coupons.
Enter Honey.

Honey is a Chrome extension that searches the entire Internet for any and all available coupons and will automatically apply the best ones to your cart during checkout.
Apparently, Honey was created by a Dad with three little ones who wanted to save some dough on pizza (pun intended) but didn't want to search for coupon codes. It searches for coupons overtime you shop online, which proved helpful this year when Christmas shopping.
Here's how it works:
Honey pops up at checkout and asks if you want to check for some savings. Click yes. DUH.
It tests for the best possible coupon codes that currently exist. In the end, saving you both money and time. BOOM.

Do you have any other tips or tricks to saving money online?
Hope your 2017 is off to a wonderful beginning:)
