Costco: $200 Costco Card When You Add A New T-Mobile Line And Bring Your Own Device + Potential $100 Rebate
Until tomorrow, November 25th, 2020, Costco has a T-Mobile promotion where if you bring your own device and activate a new line, you can get $200 worth of credit at Costco.
Currently T-Mobile is running a number of promotions including trade-ins for the new iPhones as well as activate two lines and get a 3rd line free so you might be able to stack the deals somehow.
Additionally there’s a T-Mobile promotion right now to get $100 rebate. Instructions on how to get your SOC code and port your lines over here starting tomorrow, November 25th, 2020.
If you can get this to stack, you could get up to $300 back and a free 3rd line.
