[Expired] Costco In-Store: BOGO T-Mobile Samsung S20, Plus Samsung Credit

Update 2/24/20: The BOGO is now live through the 27th. Additionally, you may be eligible for a $100-$200 Samsung credit by pre-registering your device. Hat tip Slickdeals. (Not sure if the March 6th stack will work since they may not allow stacking the deals, as per the update in the Slickdeals thread.)

The Offer

Via Slickdeals, on March 6th, T-Mobile stores will be running the following two offers:

  • Buy 2 Samsung Galaxy S20 in Costco stores on March 6th and get a $900 Master Card after rebate when adding 1 new line as an existing T-Mobile customer or adding 2 new lines as a new customer.

Here are the prices: S20 is $899, S20+ is $1,099, S20 Ultra is $1,249 (S20 Ultra is $150 less then normal). So if you buy two S20s, you’ll essentially be getting one free since you’ll pay $1,800 and get $900 back as a Mastercard.

Separately, they have a trade-in offer on March 6th:

  • Get up to $500 back when you trade in your old phone. The new phones get $500 trade-in value and older phones have lower values. The trade in credit comes partially in form of bill credit and partially in form of Mastercard gift card.

Our Verdict

Sample deal scenario: if you currently have a Galaxy S9 ($500 trade-in value), you can trade that in, and you’ll walk away with two S20s for just $400 since you’ll pay $1,800 and get back $900 rebate + $500 trade-in credit. You will have the cost of adding a line, though, so that’ll increase your costs a bit; you’ll have to keep the new line for a few months (until you get the rebate, I think?).

Even better would be if you can trade in two Galaxy S9’s and get two $500 trade-in credits. I don’t know if that works, but if it does you’ll walk away being paid $100 to trade in your two S9s for S20s. You’ll pay $1,800 for the two S20s and you’ll get back $900 rebate + $500 trade in + $500 for the second trade in. (There is the cost of the added line for a few months, but overall you’ll probably end up a bit ahead and you’ll have the updated phone.) Let us know if you try this.

Hat tip again to SD

Went to Costco store today. For Tmobile they said you can open a 2nd line but have to keep it open for at least 6 months, and they only showed me the Magenta plan which is $120/month. The guy at the store basically said you can get the 2nd device and sell it online lol. Now I have Simple choice plan which is like $50/month, I wonder if i have to upgrade to the Magenta in order to be able to open another line… Also how much can I sell the S20 for on ebay? I’m looking to make as much profit as possible.

Is the Buy-One-Get-One still available? I thought it was available in Costco until March 5th. Is that not the case?

I think the trade in offer needs to be in big bold faced letters that the trade-in happens on March 6th. I thought they were accepting trade-ins during preregistration. The guy at my kiosk told me that you couldn’t stack the offers. So, I’m assuming you do the stacking when you pick up your phone. Anyways I “pre-pre-ordered” four phones, hopefully successful DP for the trade-in.

As mentioned, they put part of the trade-in as a bill credit, which goes away if you cancel that extra line. But, as cell phone deals go, that MasterCard gift card is golden. Now if only I could switch carriers. I wonder if you could finagle a 55+ person to sign up for the Essentials Unlimited 55 plan ($55/month for two lines) to further drive down costs, at least for a new account.

Any idea if I could get a similar amount of tradein value for a Note 8?

[edit: sorry I just noticed that the SD thread has the list – never mind]

This seems interesting, but overly complicated. Maybe I’m just slow, but I don’t understand how it works 🤷🏻

They are 2 separate offers, as of right now at least.

I have a pixel 3 that I could trade in. I only want 1 new phone, I don’t want to add a line. Yes, I have TMobile. I need to go to Costco to buy the phone? Or the T-Mobile store? Or it’s online? Or all 3? I gave up trying to figure it out 🤷🏻

Haha happy to help Parts Unknown

Yes you have to goto Costco to buy the phone. You maybe able to “reserve” it by calling your local warehouse and pressing 1 and asking for the wireless department. They would take down your T-mobile account info and reserve one for you that you can pick up in March.

Since you are doing the trade in deal, you don’t need to add a line at all. You will get a shipping label at Costco when you buy the phone and then you ship that phone out. They will need the IMEI of your Pixel 3 to actually do the offer. After which you will see a $80-$90 bill credit from T-mobile and then you will get the difference in the form of a mastercard giftcard after 6-8 weeks.

Dont think the trade in is stackable this time around.Also there is a pre-register 100/150 off that needs more clarity if it can be done via costco or is a stackable?

I can explain that Aki .The $100/$150/$200 Credit is actually given by Samsung. You just enter your IMEI at https://samsungpromotions.com/ after you get the phone and they email you the code/coupon within a few days.

And Yes, if you do the $900 back offer and get 2 phones you will get the credit twice. This credit doesnt have anything to do with Costco directly even though they make it sound like that.

Thinking about doing this… Question though. I only need one; is there any reason why I can’t do this as an existing T-mobile Customer:
Trade in my S9 for $500, buy the two S20s for $1798, receive the $900 mastercard. Cost of $400 for both phones. Add a new line for 1-3months then cancel the line(wait for $900 mastercard). Sell the second S20 for ~$800 through offerup/craigslist/facebook. Now $400 earned, subract $120 ($40/line @ 3mos). $280 money maker.

In summary: Free upgrade to Galaxy S20; ~$280 moneymaker after 1-3months of service @ $40/line.

I realize these calculations don’t include taxes, so the numbers will be a little different; but it looks like I should still net positive still.

I was just thinking about this! But if you open a new line arent you supposed to keep it for at least 24months? So it pays off the 2nd device right? Will it be easy to just cancel it? Also can I open a new line for myself or does it have to be on someone’s name?
