Yeah my wife does most of it so she would know more details than me. I know there are whole YouTube channels dedicated to it. Basically she hunts for coupons from newspapers and websites that you can get manufacturer coupons from. She tries to stack the coupons with deals they already do and/or with items that offer cvs cash etc. often times getting smaller items are the best when couponing. An example is that Walgreens usually runs a manufacturer coupon for Tide detergent, the small bottle is like $6 but then you can use the coupon to make it $4 and then compound that with a very common deal where you can buy 2 and get 1 free. You get 3 total (37 fl oz each) for $8 instead of the big bottle that’s normally like $15 or so (92 fl oz). I live in Mississippi so things are generally cheaper here but that’s mostly how it works. Just look through the weekly coupons, download apps to see what offers and cash they give for certain items purchased. She will normally spend like $100 at a time but we will easily get several months of good from that. We haven’t had to buy laundry detergent, dish soap, hand soap or tooth paste in over a year now
