What are simple ways to save money on groceries?

Plan your meals before shopping and make a list so you only buy what you need. Shop with a budget in mind and stick to it. Buy store brands instead of name brands since they're usually identical in quality but cheaper. Use coupons and take advantage of weekly sales, and try to shop at discount grocery stores like Aldi or Lidl when possible. Buy staple foods like rice, beans, pasta, and oats in bulk since they're cheap and last a long time. Reduce meat consumption or buy cheaper cuts. Avoid shopping when hungry because you'll impulse buy. Check unit prices rather than package prices to find the true best deal, and freeze items before they go bad to avoid waste.
