Dell gift card and
3 months PS Plus automatically added in cart during checkout. Note that the Dell eGift Card promo code is sent within 10-20 days after purchase and carries a 90 day expiration. Good basically for two additional PS4 games from Dell.
Update: 3 months PS Plus (value at around $18) is no longer available but the giant $100 eGift Card is still working. Need an extra controller? Check out this deal also on Dell ($10 off plus $25 eGift Card).
