TM's cost of the products is no doubt much less than the $30 number. That is the street value of what they are giving away; not what they pay. I would not be surprised if many of thefreebie's cost were absorbed by the supplier as an advertising cost since they now have the potential of reaching millions of T-MOBILE subscribers and getting a bunch of data on buying habits and response rates for future marketing efforts.
I could not d/l the app so I have a question: must the freebies be used on Tuesday's? If so, they are building traffic on a slow day so it doesn't cut into revenue on high sales days; for example how many people go to a movie on Tuesday vs the weekend? Depending on the contract with the movie distributed the free ticket may have no cost since it adds no revenue and theatres often split the revenue from ticket sales with the distributor and not pay on a per person basis.
In addition, the additional traffic will bring in some increase in sales of high margin products such as drinks and popcorn; or soda and breadsticks along with a pizza. Most people who use the freebies aren't likely to change their basic buying habits, so if they usually get a soda they probably still will. Some may even buy more since they have not spent money on a pizza or ticket.
In the end, I'd be surprised if the promotion costs TM much money relative to revenue.
Now we are entering speculation territory moreso than before since non of us have numbers ( assuming they make those public at TMO or these partners )
That aside normally Tuesday ONLY But supposedly ( according to some confirmed by the app to a degree ) the date was extended thru 5am this Thursday ( local time at whatever location you're redeeming it )
Anyways I'm mostly done and over this topic and thread ( mostly this thread ).
We shall see what happens in the coming weeks, months , years etcetera
