Aldi recently dropped the price of their Millville Protein Chewy Bars to $1.75 for a box of 5. The previous every day price used to be $2.19. Flavors are Peanut Butter and Dark Chocolate or Almonds and Dark Chocolate.
This is basically a store brand version of the Nature Valley Protein Chewy Bars that are regularly priced around $3.50 and typically go on sale for $2.50 at major grocery stores.
I can't speak for the ingredients but they have 10g protein, 7g of fiber and 6 or 7g of sugar so they look relatively healthy for a bar like this.
edit: I should note I have seen this price at multiple Aldi locations in Maryland. It may vary by location though.
