Looking to come back to TMobile, any tips? Hints for discounts?

Had TMobile years ago while I lived internationally and it was great. I then moved to a rural part of the US and the coverage didn't work for me, so I switched to ATT. TMobile has made some moves in my area and the coverage is probably better than the other companies at this point. So, I'm looking to switch back. I'd only be looking at 1 line and 5G home internet, plus a new phone. I currently have the following in my cart: Experience Beyond 2.0 iPhone 18 Pro 256gb Amplified Home Internet I used Work Perks to get a discount as a teacher and two other coupons I found online. It is giving me a total of: $122.41/month and 524.26 due today with the phone down payment. Thoughts? Decent set up? Am I missing discounts? Would I be better off going into the local store and seeing if the reps there can get me further discount? Or would I lose out on the deals I currently have in my cart?
