for iphone, Apple online or retailer is cheaper?
Retailer will definitely be cheaper if you can get the discount, but you have to purchase the iPhone with Apple Care+ together on the spot. After sales, those who want to get Apple Care+ have to call Apple.
For iPhones/iPads - 5-10%. (Usually 5% will be given for iPhone and 10% for iPad)
For Mac - 10% is the ideal. (15% if Sales person is willing to forgo his/her commission for you)
