The Double Chalupa (which looks like a Chalupa boat) features an oversized Chalupa shell filled with a double portion of seasoned beef (compared to the Chalupa Supreme), shredded lettuce, diced tomatoes, three-cheese blend, reduced-fat sour cream, and nacho cheese sauce. The suggested price for one is $3.49 (may vary).
You can also get the Double Chalupa as part of a $5 Box (may vary) combo with your choice of a Double Chalupa or Spicy Double Chalupa, a crunchy taco, Cinnamon Twists, and a medium fountain drink.
When purchase the Double Chalupa Box (or Grande Nacho Box), you also get a chance to win an Xbox One X Limited Edition Bundle, which includes an Xbox One X Eclipse Limited Edition console with Taco Bell's iconic ring at startup, the brand-new Xbox Elite Wireless Controller Series 2, and a six-month Game Pass Ultimate membership. They'll be awarding one about every 10 minutes or so through November 23, 2019. There's instructions on the specially-marked boxes (while supplies last) on how to enter. You can find the details on their website here.
