1. Read the Publix sale paper
2. Search coupon database
For Southern Savers, simply enter in the brand name of whatever item Publix has on BoGo and the coupon database will pull up every insert that it was in, along with any store coupons that are available, AND any Ibotta deals. SO EASY! Southern Savers has a great little feature where you can choose your local newspaper and they'll tell you if your paper carried that coupon. Just be aware that coupons and Ibotta deals can be regional, so if you see it on the database, but not in your paper, it may not have come out in your area, it may have been reported without being printed, or you may be missing an insert, an all too common occurrence in the couponing world.
Bonus Tip: The Southern Savers app looks almost exactly like the website and is just as easy to use.
3. Check your rebate apps
4. Make your list and go to the store
Important Tip: If Publix is out of the item you have coupons for, go to the customer service desk and ask for a rain check. Even if your coupon and the sale have expired by the time the item is back in stock, you'll be allowed to redeem it at face value for the item's sale price.
