weird iphone sale in U.S.

This very few days are American important Thanksgiving  deal days, called Black Friday. But it's not only one day deal, usually it only last several days from Thursday.  One friend in China wants me to buy a iphone6 and mail it to him.  I looked at the price of gold iphone6 16GB without contract and 16 GB -- 649 dollars in online Apple store. It made me surprised, There's no any discount for iphone6 at all even at Black Friday.  Apple is really different!

Then I went to go to a big Mall to have a look and decided to take it. When I went to the real Apple store and checked the price, the same price as online Apple store,  but they don't have the gold color with 16GB. So I went to other stores like AT&T,T-mobile, but they don't have iphone6 without contract now.  Lastly I went to Best Buy-(American biggest electronic chain store). I talked to them about all the requirement, luckily, they had what I wanted.  When everything was ready, I found the price is not 649, it's 699. I felt surprised and asked them why  the price is not 649?  They asked me whose price is 649, I told them it was Apple store. They helped me checked for a while and then told me here is 699, different from Apple store. To my big surprise again, Its price is even higher than the official Apple price. It's unbelievable that if that happens in China. Usually, As far as I know the official price of something is the highest one, we always escape the official sale if we could find cheaper ones.   If the Best Buy's iphone is more expensive than that in real Apple store, who will buy their Iphone?
