Cartwheel will save you money, it has discounts for target like 5-50% off certain items in the store. All you do is add the discounts you want to use and it gives you a bar code for the cashier to scan. That's it.
WellSpent is a bit different than the others, it's a budget app. I find that if my money is budgeted I won't spend extra on something. It's nicely set up, colorful, easy to use, and the best part is it's free.
I'm excited about this—I'm starting a monthly newsletter. You'll get an email at the end of every month with all the months posts, updates, and a quote. If your on the computer there's a sign up box in the sidebar, if you're on your phone switch to the web version, then sign up in the sidebar. If you have any questions about it feel free to comment or email me.
Don't forget to comment & sign up for the newsletter. Have a great week! :)
