Actually, I think Costco had one of the better deals around. My carrier is Verizon so all I would've got from them was BOGO and the headphones or Fortnite offer. BB was offering the same with a $100 gift card. Costco, on the other hand, had the same BOGO deal, the same headphones or Fortnite offer *plus* a $150 Costco cash card per line activation ($300 to me) and a travel accessory kit per line. I'm happy. Picked up my pre-orders yesterday. I did buy the Square Trade warranty and have 90 days to think about it. By buying the warranty the same day the phones were purchased, the warranty will cover either phone if needed.I don't see anything extra from Costco, that you can't already get directly from the carriers.
