If you want to get a fair price at Dominos, you have to play their game. At least look through the website for special offers on pizza, because the "menu prices" are 2.5x higher than the average price a person pays. After that, if you still want a lower price, search the Internet for coupons (although that doesn't work as well nowadays since they use account-locked rewards systems instead of coupons).
Even if you play the game, it will still be more expensive than you remember, due to massive inflation.
I don't go to Dominos any more due to repeated bad customer service, their website malfunctioning in a lot of ways, and the last time I visited the store it smelled strongly like ammonia.
