NOTE: This will work but it just depends on your Pizza Hut location.
“There’s 5 steps you have to do: (If Step 1 shows “invalid code” then your restaurant doesn’t work, sorry)
Step 1: Go to PizzaHut.com Use code 65 and follow instructions to add a 1 topping pizza hand tossed or pan pizza to your order.
Step 2: On the menu tabs, one of them says “Tuscani Pastas”. Add a 1/2 order of any pasta to your order, when asked if you want breadsticks or cheesesticks, click breadsticks only.
Step 3: Enter code PM
Step 4: Enter code IF and order free breadsticks.
Step 5. Delete the Tuscani Pasta from your order. When you do this it causes a glitch in the system and will give you both orders of free breadsticks AND the pizza for only $3.29!!”
Let us know if it works for you!
