I've been thinking about upgrading my phone for a while, and seeing this KOODOOFFER code seemed pretty attractive! I added a Google Pixel 3 to my cart and added the promo code, but nothing seemed to come off. I have a $50 plan which i'm not changing.... My tab was at 0 but am now adding a small tab of 240..... but even when i enter the promo code it says my monthly payments will be $60. I understand it is not a new activation, but this is an upgrade to a new phone. Could someone let me know if there is other fine print i'm missing. Thank you!
