Deal Details
This only works if you have an eliginle trade-in device. For example, Samsung Galaxy S24 Ultra or S24 Plus (I tried these 2, they have the same trade-in value)

T-mobile is running the Get up to $1,100 off with trade-in on an Experience More or Experience Beyond plan. Offer Id: Samsung Galaxy Promo with Trade (ID260641)

I was able to trade-in my Unlocked Samsung Galaxy S24 Ultra 256GB for S26 Ultra 256GB for $45.64 Monthly store credits for 24 months. After trade-in credits, the S26 Ultra 256GB ended up being $8.24/mo for 24 months or $201 total.

Costco T-mobile gives you a $100 Costco Gift card (waiting period 16 weeks after activation) for new device and waives the $35 connection fee. So after all said and done, my total was $1300 - $1100 (in credits) - $100 gift card = $100. The tax is added on the full phone price and is different per state requirements. My tax was $81.25.

Here is how to get to the deal (if you are ordering from Costco):
  1. Start with this https://www.costco.com/f/-/t-mobi...d-showcase
  2. Log into your Costco account
  3. Scroll approximately 1/3 of the page down, until you see the Upgrade your device offer under Costco member benefits.
  4. Click Upgrade Now button, then Visit External Link
  5. Log into your existing T-mobile account and ensure Costco Banner still appears at the top.

I was on the sprint sero plan back on my flip phone. It's amazing that people think they're getting a deal on grandfathered plans when they're being overcharged for the last 20 years 😂

This is a useless comment. The deal is not a discussion about the plans. The deal is about swapping a 2 year-old phone for a new one for $100. Looks like some reading and comprehension work is needed here

OK, so direct linking does not work. Try this instead:
  1. Start with this https://www.costco.com/f/-/t-mobi...d-showcase
  2. Log into Costco account first
  3. Scroll approximately 1/3 of the page down, until you see the Upgrade your device offer under Costco member benefits.
  4. Click Upgrade Now button, then Visit External Link.
  5. Log into your existing T-mobile account and ensure Costco Banner still appears at the top.
I will update my original post with this

Your deal is bad on so many levels. First the Experience plans are expensive, then you gave up a S24 Ultra.
Perhaps if you have a family plan of 4 and a S20 to trade in

Only $500 off for my Experience Signature military plan. Same deal It's been for a few years now.

Though I do only pay $24 a line, so the poor promos have come to be expected. Other than the free pixels, and the $930 off I got for an iPhone 18 Pro pre-order.

Can you explain, how is paying $40 a line with 5 years price lock on Experience More is expensive? Also, what is wrong to give up an S24 Ultra? Other than the stylus the S26 is better and faster (not by much but still)
