Couponing saves us thousands every year and I usually only e-coupon so I can sit down and watch TV, click on the sites, and its loaded automatically to my customer loyalty card.
Some examples this last trip comparing to Walmart/Dollar General/Amazon, I was able to get these on sale, plus at least one coupon, often doubled up with Ibotta
El Paso Enchilada kits for $1.28 vs. $3.50-4
Nellies Free Range Eggs for $1.34 vs $3.99-$4.99
Arnolds Sandwhich Thins $1.12 vs. $3-3.50
Tide 40z HE Oxi was $1.61 vs. $5 (figuring 25 loads thats 6.4 cents a load)
1. Ibotta (its a mobile app that you either link your card or scan your receipt) Best part is its coupons AFTER the purchase so it avoids the no double coupon rules. They also have "ANY" coupons so get 25 cents of the purchase of any butter. Checkout51 does the same but tends to be more pet food, baby stuff, and junk food which I don't use any of.
2. The web site of the store usually have e-coupons these days (often they use the same service as Coupons.com, typically you can only use one but if they have things like Buy One Get One, print 1 coupon, use the e-coupon for the second.
3. I also use rebate sites like MrRebates, Ebates, Swagbucks if I am buying online, like today Swagbucks applied a $5 rebate to my Chewy order.
4. If you have a specific grocery store, I suggest you google "X deals" and see if you can link directly to a couponing site. Like I use Harris Teeter Deals, and there is a person that takes every ad, every week, cross checks prices plus coupons and then provides a spreadsheet, so you just need to go to the spreadsheet and it will show you where to get the coupons from. I know there is one for Lowes Foods also, so I imagine there are others. Its lazy couponing, someone else does all the work figuring out the deals.
I shop a lot at Aldis and ethnic stores, but still buy meat, paper, cleaning elsewhere and certain snack foods and thats where couponing comes in.
