I know it sounds confusing but, allow me.
First add the Samsung Galaxy Luna pro ($60) to cart. Will be free when you add the $25 plan or higher.
Then add a second phone but choose "I don't need a service plan", I added the refurb 32GB iPhone SE (which is only available thru Total W) for $80.
You will see a $120 discount. My total was $45 plus tax ($25 for the plan plus $20 for the SE). Free ship
NOTE...you can get an extra $60 off for each Luna+Service card you buy. Say Two Lunas+two service cards and two SEs come out to $88. A $240 discount. I believe they have a 4 device max.
