If you have the Amazon prime visa, it’s more advantageous to buy through Amazon for the 5% cash back.
Depends on the model you're buying. Many credit cards give 1.5% or 2% cash back, so you're getting an extra 3% to 3.5% with Amazon Prime Visa card.
Compare the prices with 5% cash back (CB) from Amazon Prime Visa vs prices with 1.5% cash back (CB) from most other credit cards (all before tax)
It's only less with Amazon Prime Visa if you're buying the first two 14-inch MacBook Pro models. Every other model will be less from Micro Center (or Best Buy price match) with a 1.5% cash back credit card.
I don't believe taxes would change things.
