I have written before about Amex Offers, but there is a great one going on right now for a limited time – $15 off $60 purchase at Amazon.com
To load multiple cards
If you’re wanting to load multiple cards, you need to load up multipe tabs and switch to each different card in a different browser tab, or otherwise American Express will only let you load the offer to one card.
Oftentimes you can load your Amex Offers via Twitter, but it does not appear to be working via Twitter yet. This is actually probably a good thing because with as many auto-sync programs there are, it tends to make the deals run out pretty quickly (there’s usually a limited amount available)
I was able to sync all of my cards this morning but if you’re reading this post later in the day or on Tuesday, it’s likely to be sold out by then.

So I have to open 4 tabs since I have 4 accounts but have each one wit the card I need to load? Then I click the offer and it will load it on all 4 at the same time?
Correct. Open up 4 tabs, and then choose a different card in each tab. If it’s an offer that each card is eligible for, they should all show up, and then you can add it to each card
