Here we have Sam's club. They're kin to Walmart. Buy things bulk, separate into serving sized bags, and freeze if at all possible. Meat, vegetables, even cheese and milk. Look for sales. When you go in the store eat all the samples that you can get. Some people go in hungry( big mistake), and come out full. There's savings right there. Just don't go there every night, treating it like an all you can eat buffet(just kidding). In the grocery store, look for things marked down because of expiration date, and freeze "time".
Don't try the truck gig, it's not a good idea. Cook things like stews or soups. They go a long way and you have leftovers, or enough to freeze.
There are multiple sites that offer coupons and free samples. Like dish liquid, laundry detergent, toothpaste, etc.
