I need to buy an iPhone 5 by this weekend - costs around $650 for my wife as a gift. I am not sure what is the best way to buy this and maximize miles.

I am thinking of going for 3 different staples $200 gift card - each from a different physical store - which gives me $15 off each card (if that is allowed) and gives me 600 X 5 = 3000 UR points.

I can go into an apple store and use three visa gift cards to purchase - is that correct?

Any other creative ways?

I also have Freedom card and HHonors card - both giving additional points for drugstores spend
