There’s a targeted Amex Offer found on some business cards to get 20% back on a in-store purchase at Sam’s Club with a maximum of $250 cash back. We wrote about it in these two posts:
The key here is that the offer is only valid on a single purchase, so you’ll want to spend $1250 in one transaction to get the full $250 back. Many have noted that, in practice, doing multiple back-to-back transactions (probably anything in the same day) also works to trigger the offer credit. This makes it easier, especially for variable-load Visa gift card purchases which require each $500 card to be processed separately.
Visa/MC gift cards and Sam’s Club gift cards are the easiest way to maximize. Some people are getting cashiers telling them that they can’t take credit card on gift card purchases, but I think most people aren’t having that issue. Try the customer service desk if a regular cashier doesn’t work.
The offer expires on January 31, 2017. So long as you swipe the card before midnight on 1/31 it will trigger the offer credit.
I don’t know if this offer is still available to save now, but if you saved it previously you can use it until that date. Interestingly, people have been reporting over the past month or two that the offer was continuing to pop up in logins that hadn’t seen it before. So it might still be available for saving and might even have popped up since you checked last.
This is the most profitable Amex Offer I’ve ever seen on a card-per-card basis. Of course, it’s less scalable than other offers since it’s only found on select business cards.
