So I've been thinking about getting a new Mac! Yah! So looking around through discover I could get 5% through shop discover, 5% through the cashback bonus up to $1500, and 2% back on Oct 26th through the double cashback day. My question is has anyone had any luck combining this with corporate discounts or educational ones as the 5% shop discover says you can't use it with any other promotion. If you could that would be sweet. Math: $1597 13' Retina Macbook Pro through corporate discount - 75.00 Cashback - 79.85 Shop Discover - 31.94 Double Cashback promo = $1410.21 All picked up in a state with no sales tax, and minus anything I can get for my existing macbook.
