“Free $100!” AMEX Platinum personal card has a Dell offer: spend $100, get $100 back — “free Gold authorized user cards may have it too”

[Update] Based on author KUKU’s experience, free Gold authorized user cards may also have this offer. If you previously added a Gold authorized user card for a family member, remember to check it too — don’t leave free money on the table. It also seems possible to get the offer even after adding a card temporarily, but YMMV. (If a newly added authorized user card cannot be linked to your existing online account right away, it’s probably not worth the hassle; just check the offers on older authorized user cards instead.)

Free money, free money! Many AMEX Platinum cardholders have received an AMEX Offer like this: spend $100 at Dell.com and get $100 back.

What to buy?

Dell doesn’t just sell computers. It also carries all kinds of computer accessories (mice, keyboards), gaming products (Xbox, PlayStation, gaming peripherals), and office supplies (printers, etc.). Even if you don’t need a computer, there are still plenty of worthwhile things to buy.
