Not sure if this is the right forum, and search turned up nothing.

I'm going to be buying a new Apple computer sometime in the next year. I know if I screw it up I could end up getting 1-2pt/$, but I was wondering the best place/way to purchase. I'll be spending around $3000 so the difference in pts/$ is definitely worth some research & planning imho.

I'm looking to get Chase UR points or United miles.

For example, I just bought an iPad Air from Staples through the Mileageplus Shopping portal using my Chase Ink card, so I got 9pts/$. That's a huge difference, and with a computer it would be an even more important difference.

Problem is office supply stores don't sell Apple computers, only some of their devices. The Apple Store (not the iTunes store) is on MileagePlus shopping and Chase UR portal for 1 point usually (every now and then 2). I've never seen it higher than 2.

Also they don't sell Apple gift cards at office supply stores, so right now it's looking like the best I could get is 3.5 miles (2 from a portal when there's a "sale" and 1.5 from the United club card). I'm looking to hopefully get 5+/$ if possible.

My cards:
Chase Ink
Chase Freedom
United Club Card

Thanks!
