COSTCO BYOD - Get $300 for adding a T-mobile Voice Line (Stacks with New 2022 BOGO line offer)

+27 Deal Score
COSTCO is again offering the $300 Costco Cash Card rebate for adding a new line to your T-mobile voice plan and showing proof that you have an eligible 4G/5G smartphone for the new line of service. I was able to add 2 new lines today.

PROMO CODE: M00006306
Promo Start Date: 1/1/2022
Promo End Date: 3/30/2022
Promotional Rebate: $300 Costco Cash Card
Limit of 2 rebates per account

[Edit:] BYOD rebate appears to have been renewed for the period 4/1/2022 until 6/30/2022. Those who did this for Q1 2022, you can do it again fo Q2 2022 up to 2 lines. Note that there is no new BOGO voice line. So if you got the BOGO free line already in Q1, there's no additional BOGO free line for Q2.

Other Notes:
  • There is a new T-mobile BOGO promotion for voice lines that stacks with this. When I added 2 new lines today, my account automatically showed that the 2nd line added is free ("2022 Line On Us P1") with no additional action required.
  • Per T-Force, the BOGO voice line promotion excludes Military, 55+ and First Responder plans. Also, the BOGO line promotion is only available to existing customers. New customers do not qualify (but new customers under the Magenta plans do have the 3rd line free offer which also stacks with this).
  • $300 Rebate is a Costco Gift Card and can only be used at Costco.
  • Rebate takes up to 14 weeks of processing time. This means you'll have to keep the added line open during this period until you get the rebate.
  • You may be charged $7.50 for the T-mobile SIM card. My BYOD phones were new phones that already came with their own SIM cards that are ready for activation so I was not charged the additional $7.50.
