The available Snack Stash mix-and-match choices include: Onion Rings, Waffle Fries, 6-piece Jalapeno Poppers Bites, small Fries, or Fried Zucchini.
Prices vary but the deal provides a lot of value at my local Carl's Jr. in Los Angeles. Sides here range from $3.59 for small Natural-Cut French Fries up to $5.99 for Fried Zucchini. If you opt for three orders of Fried Zucchini, it's a "buy one, get two" special.
