Best discounts for Walmart ?

Okay so I usually shop at Walmart because I have an associate discount card and I get free Walmart +. Where can I get even more discounts and coupons so my weekly grocery haul is discounted even more ? I figured I would ask you guys since you’re experts. I always buy large slabs of lean ground beef, fish , chicken breasts, ground Turkey , produce and rice because I’m sticking to a strict diet. My goal is to save more money every week. I spend around $130 on all the food I eat throughout the week and I would like to get that number down even more.
