Clip Coupons
You won't believe how much money you will save if you take the time to go online and see if the store you're going to has coupons. One time I was standing behind a couple at Target near Christmas time, and they brought up their Cartwheel app and saved around $60 on toys they were getting their kids. After I heard that insane amount of savings, I downloaded the app then and there as their items were being bagged. 

Take the time to see if the grocery or big box stores you're going to have any deals, and get the appropriate clippings for them.
