Considering Apple insists on not building an Apple store anywhere near me, making it a 2 hour+ round trip affair to go the store. Also, Best Buy would give me back $250 back in gift cards after a big purchase like the iMac pro... I don't think Apple does that. Even my best cashback offer on a credit card doesn't do 5% rewards...
The best place would be to order out of state like bhphoto to save 10% sales tax that I'm paying right now...
