Buy 1 Get 1 FREE Dominos Pizza Promotion Experience

During the night, I just ordered the Buy 1 Get 1 FREE Dominos Pizza promotion as my dinner. I just key in "RLNR" for regular size pizza in their system and check out.
The pizza arrived in time and I enjoyed it.
Somehow I just spend my day in Malaysia instead of traveling oversea. I have a RM50 "Ye Zi" (椰子) restaurant cash voucher but didn't use it as below.
