Non food items for almost free or free.

You can save on food, and I only buy food at the grocery store, pretty much.   There is always an exception.   I got deodorant BOGO at QFC and used a coupon for each .  Not every store will allow you to do that, but it doesn't hurt to ask,  net result was paying a quarter each for two deodorants.

Pretty much you should never buy personal Heigene products and cleaning supplies at the grocery store.   You are cha chinging their bottom line, not yours.  

I get almost all of those kind of products for free or nearly free.  

1. Feminine pads are 330 for 48 at the big lots.  Twice a year everything in the store is 20 percent off.   
2. Toothpaste, toothbrushes, and mouthwash are free at either  the dollar store, or at the chain drug stores with rewards.  Rite aid is easier than Walgreens.   
3. Ibotta earns you money on gift cards for buying what you normally buy anyway.   That buys a twenty five dollar card from Amazon and toilet paper can  magically appear on your doorstep.   
4. Shampoo, soap, can be cheap with coupons, or free from the dollar store.   
5. Vinegar is close to two bucks a gallon at Costco in two gallon boxes.   Many things can be cleaned with vinegar.   
6. Other cleaners are at the dollar store for far less than their name brand counterparts.   Bleach gel is one of my favorites for the sink and countertops.   
7. There are school bus yellow rags in bulk at Costco in the auto section.   They do wonders to replace paper towels.   There is a cover for food in the microwave at the dollar store.    We make a case of paper towels last a year at our house.    Paper towels are cheapest and won a pick up challenge at dollar store.   A name brand basic bounty . 
8. Shampoo is at the dollar store.   We don't use conditioner.
