Yep. 10% of 3079.84 is.... $307.98 Total savings: $653.58 (19.08% of $3425.44) The Story... Well, I thought I could make a BTO purchase by buying gift cards via Apple Pay... at least that's what the Apple girl told me. It wasn't until after the fact that I realized that Gift Cards tend to have stipulations, and with a paranoid call to Discover, they informed me that purchasing Gift Cards indeed do not reward cash back. So I got on the phone with Apple and explained the situation. We talked through how best to handle it, since it's such a weird case. It turns out that when I receive the computer, I can return it to get the money loaded back onto the gift cards. Then, I'll return the gift cards. Finally, I'll purchase the computer back outright directly via Apple Pay, now that the model has an order number that can be "scanned". And that's the good news of how I saved 19% by switching to Apple Pay.
