I got an invitation from Apple today to apply for the Apple Card. I don't think there's an interest free promotional period. According to Apple the interest is variable with a "range from 12.99% to 23.99% based on creditworthiness." If you want to finance a Mac Pro the better option may be the Barclaycard Financing Visa which has an 18-month interest free promotional period. Of course there are several other credit cards from various banks that do also.
The other big selling point behind the card is that neither Goldman Sachs not Apple will sell any of your purchasing data to anyone. It’s the only card I know of that’s like that.
Get special financing on Apple products. Pay over time, interest-free with Apple Card Monthly Installments. And get 3% Daily Cash back with Apple Card.
