If you read the fine print on the offer it is one 10 dollar credit at each retailer perONLINE account not card account. You log into yourAmexonline banking to use the feature. Therefore if your cards are all linked to the same account I do not think you'll be getting more than one refund.
Yeah, I agree that the fine print does read that way, but folks on the travel and 'miles' websites are reporting some success in getting it to work as long as different cards are used, so it's a little up-in-the-air right now.
Also, some folks have each card on a separate online sign-on, which should be expected to work regardless.
In my case, my second purchase was only $10 (I have two Amex cards), and I would have made it eventually anyway, so if I end up with only one freebie that's OK.
The good news is, at least in a few days, we'll know for sure 
Made three purchases in Newegg one on each card for 0.40$ on 7/14.
Got the credit of 10$ on each of my cards yesterday on 7/16.
All three accounts are linked to a single AMEX account. So apparently it works.
Now onto the TicketMaster 1$ donation so that I can pocket another 27$ into my cards.

My bad the links which were available for TicketMaster are dead now and I gotta wait till people report out some new links.

@Beckhsrules I don't think more links will help. One of the links I used to make two $1 purchases on Ticketmaster was still working. However, the Amex Checkout button was no longer there. I think they put a fix in for at least Ticketmaster specifically.
Same problem with me now. I found out a link for 1$ but AMEX Checkout is not available. But if I try to purchase ticket for a normal event like the CONCAF Final I am able to see the AMEX Checkout option. Something fishy with TicketMaster.

Did the same and got 3 credits 2 days after my purchase
