Most of the time Costco will double the manufacturer warranty, I am not certain that is the case with the iPhone, but that is typically an advantage of buying electronics from Costco.
Cheaper prices and gift cards and sometimes extra gifts
Costco sells other things that you need,food, clothes, gas,booze,dog food,pills,a phone store only sells phones!
Promotions: always better than buying it at phone store.
Most of the time they will give you more warranty than any other store will I don't know if that's the case when you do buy a iPhone
