My go to for cheap is eggs!

If you shop at the 99cent store they have good prices on limited quantities of bacon, ribs, sausage, cheese, half n half, cream cheese. Package of avocados 4 for $1.00. Recently clearanced ripe strawberries to 25c a carton. Loads of veges there. 3 packs of seaweed and flavored and unflavored pork rinds 1.00.
