I use the store's bonus card and I clip weekly coupons, but only for stuff I know I'll use or stuff I'm trying to slowly accumulate, since I'm working to outfit my future home. I will also clip one if I think I might get it to donate to the local women's shelter or food bank.
What I save through those two ^^ methods I then put in my Roth IRA at Vanguard every week.
I also use Ibotta and I've earned $125 since January, very happy with it. I've downloaded Checkout 51 and Berrycart but don't find them very helpful and probably won't keep using them. The $ I get from those two is not worth the time.
I use the store's app, too, and find it mostly helpful. For example, this week I can earn 4 times the gas points with the app coupon, which is very helpful since I live in Pennsylvania, the Land of High Gas Tax.
All told, I spend maybe half an hour a week going through all that. When I stop using those two apps I'm not happy with it will be a lot less. I do use coupons for other stores, too, but I only shop for clothes and Things (with a capital T) every couple months, so....
