Here is what I did. Ported my line from Cricket to avail this $300 Costco shop card offer. Then bought Samsung Galaxy Note 20 Ultra (T-mobile) from Samsung website using student discount https://slickdeals.net/f/14880388-samsung-trade-in-galaxy-s10-series-get-128gb-note20-ultra-t-mobile-smartphone-278-free-s-h-more?src=SiteSearchV2_SearchBarV2Algo1
for $334 ($278+ 56 (tax)). Basically, if everything works out and I get Costco shop card, my cost for a new Note 20 Ultra would be $34.00
Nice choice

Wow, so you could have ported in 12 different lines or purchased 12 handsets and they would have honored the rebate 12 times? $3600
I did 15 for $300 per line on Sprint a while back. And ohh boy that was sweet!

I posted this on the BOGO iPhone 11 thread deal also through Costco but say I port in 2 lines on this deal for the GCs, which now makes me an existing customer. Then add a line for he BOGO deal for iPhone 11. Will that work?

Did anyone have a problem with the rep not being able to print out the rebate forms? The manager came over and said that happens quite often and was gonna submit it manually. I'm feeling uneasy about it.

Questions for those in the know.

Do I get an account with 1 line opened at tmobile first, and then add 2 lines to it at Costco?

I want to play this safe and want to keep to 2 lines only for $600 max GC.

I have plenty byod devices though.

I can port in a number and don't mind getting the other 2 lines as new numbers.

What's the best way to go about it?

Also. Is it best to port in my existing att number for opening a new account at tmobile, and then add 2 new numbers at Costco?

What else am I missing?

edit:
when creating a T-Mobile account and line, what's the best offer I can use for a double win?



Thanks.

If only 2 lines per account, I am not sure why it's a good deal. You have to pay$90+tax per month for 3-4 month waiting for a $600 costco card.

Exactly my point...also it's a Costco cash card not a prepaid card like the T-Mobile deals which can be used amywhere
