An interesting thing to note regarding two emails I received from dominos.
It's along similar lines a while back where people were complaining about varying prices/offers from McDonalds.
On 1 account, i received codes for 3 Pizzas 3 sides for $34 delivered, $29 pickup.
A few seconds later I also got the same email to the same email account using ±dominos@gmail.
Same deals but $1 cheaper.
Although only $1 cheaper, just find it interesting that they are starting to do this.
I got an email from dominos offering 50% off pizzas as I hadn't ordered in a while - the code is unique. Unfortunately it doesn't seem to work (not valid at this time of day) no matter the time selected.
