holy fudge!
I think I've found the code vault! 

sharing is caring, but in this case, if I expose this, chances are dominos might find out and fix the code.
can I just keep to myself?
Yea, I wanted to try pizzahut for once. Haven't tried them for a very long time, but then someone posted the toppings for this promo, really pathetic. Can count with one hand the toppings.

ok, I give one code.

Buy 1 Large Pizza @$15

cashier too busy.. usually they dont..
imho, they dont know whether we use coupon or not, because they just follow what on system.
if system stated u pay, they will ask money from you else viceverse.

usually for me, i pay online and go takeaway.
just mention my name, they pass the pizza and i walk away, simple as that.

I ordered online, then proceed to the store for takeaway.
nop, they won't ask one.

Once your order is in the system, the outlet will honor the offer and the price. So don't worry. Dominos work via central ordering system. If something does goes wrong with your order, they will call you beforehand.
