iPhone 7 & iPhone 7 Plus @costco, you get $250 costco card after trade-in and extra upto $100 cash card AT&T and Verizon, B&M YMMV

Was at costco today and traded in my 16gb iPhone 5s for a new iPhone 7 Plus on AT&T. You get minimum of $250 costco cash card back for iPhone 5s and more if you trade in a newer model. Also, if you are a new AT&T customer, you get extra $100 cash card making it a total of $350 back after 5s trade-in. I am an existing AT&T customer, so I got $250+$25 cash card. You also get a 5200mAh rechargeable portable battery (not a big thing) with the deal. Similar deal for Verizon. Promo valid Feb 3-5th at my local Costco. So YMMV. See attached pic.
