Free Upgrade to T-Mobile One Plus with T-Mobile Business Account Activation

Since I may want to take advantage of the Note 8 BOGO, I need to be on T-Mobile One. It wasn’t worth it for me to switch until I came across this deal in the business section of T-Mobile’s website: https://business.t-mobile.com/t-m…1V4EZU9931
I’ve been on the SC 10GB plan for over a year (on the consumer side). I have 5 lines that I’m paying $140 per month plus taxes and fees. As everyone here knows, all of the new phone promos are for T-Mobile One customers only (or SC Unlimited). The old SC plans are better since they already include HD video, high speed tethering, etc. Including taxes and fees, I’m currently paying about $170 per month. The new plan would cost me $180 per month (including Plus for free) and one of my lines will qualify for the Kickback each month bringing the plan to the same price as what I’m currently paying (after the $10 credit).
I think this promo has been going on since 9/1/17 but I didn’t see it mentioned on the forums here. If you qualify for a business line (I have my own company), it may finally be worth making the switch over to the T-Mobile One plan with the Plus thrown in for free (and grandfathered in I was told). I was also told I’d be able to port over my 5 existing lines to the business account and all 5 lines will get the Plus for free.
Don’t know when this expires but I may do it in the store Friday.
