My account has 156,xxx Delta SkyMiles. The product is a giftcard which costs less than 10,000 Delta SkyMiles. What does this code mean? Tried plenty of different items.
I had this same issue and was told Delta.com and SkyMiles Marketplace are only compatible with PC computers running Chrome. If you attempt on any other device (even a chromebook) you will be locked out of your account (internally) and need to call and have a rep submit a ticket to Delta's support staff to unlock your account. Once this has been done you are able to log in again *on a PC through Chrome* and complete the purchase.
