My mistake. Its $70 unlimited for one user. Still its much cheaper than AT&T/Verizon. As long as your city as Tmobile LTE its a great deal.
I also like Tmobile because they let you bring your own phone and pricing is straight forward. AT&T does also but its very hard to determine what the monthly cost would be without a subsidized phone. Can't find it anywhere on their website.
You can't find cheaper pricing for BYOD with AT&T because there isn't any... That's the problem with the other big carriers. You're paying the price for the subsidy even if you bring your own phone or the contract is satisfied. If you want a cheaper price with AT&T, you'll have to get GoPhone, AIO or one of the other prepaid plans from either Net10 or Straight Talk (and other MVNOs).
