Twitter too is a good place to find deals, case in point, among the various annoying sponsored tweets, you may actually find something useful. American Express is running a Blue Preferred Card promotion that in addition to the regular cashback rewards, you receive 10% back on Amazon purchases, up to $200 in Rewards (= up to $2000 in purchases) or for the next six months, whichever happens first. This is great for the holiday shopping season since most people spend a lot more during that time. In addition, you may be able to qualify for $250 back when you make $1000+ in purchases within the first three months.

When you're shopping on Amazon, why not get 10% back? Now you can. Apply by 1/11/17. https://t.co/g5KPhQhTA5 pic.twitter.com/1CiPjXvFoT

NOTE that the Blue PREFERRED has a $95 annual fee. As much as you may find annual fees revolting, this is actually better than the regular no-annual fee AMEX Blue if you make an average of $265+ monthly purchases in groceries (or any other combination of bonus-percent category purchases).

This is because groceries are 3% with the default Blue. With this one, you get 6% (up to $6000 in purchases per year). So for the Preferred to be …preferable (sorry, I couldn’t resist), you need the extra 3% to be higher than $95 per year. Pull up the calculator, and the break even point is $3164 per year or $264 average per month. So if you spend more than that, you get more cashback with the Preferred even with the annual fee.

But you don’t just get more % rewards on groceries. You also get 3% on department stores and gas stations versus 2% with the no-fee Blue.

If you have an American Express credit card that has Membership Points rewards (not the AMEX Blue that has cashback rewards), check your offers. You may be eligible for a new Dell offer as you can see in the screenshot below (View Larger):

If you spend $299+ at Dell.com by September 12 in 2016, you will receive 5,000 Membership points, which you can redeem for a $50 gift card at a number of national retailers and restaurants (those that offer 1:1 points to pennies exchange). Based on the text of the offer, you don’t have to make the $299+ purchase in a single transaction, so it can be cumulative. So you don’t have to do it with a PC purchase, it could be random accessories purchased over time.

Before all that happens, you have to add the offer to your card. This is easy, all you have to do is press the “Add to Card” button.

IMPORTANT: even though the offer expires 9/12/16, it doesn’t mean the sign-up will be offered in your account until then. If you think you are going to use it, you must “Add to Card” now. They often have a limited time of sign-ups, so the offer may no longer be available for sign-ups long before it expires.

AMEX Offers are by definition YMMV, since we don’t know if AMEX makes these offers available on every credit card account or a subset of the accounts. The easiest way to find out is to logon to your AMEX account and look at the Offers section below the “Recent Activity”.

Bubbling around at the moment are two pretty good offers if you like to make general purpose purchases, especially for homeowners. As you can see in the screenshot below…

… you get $10 back on a $40+ purchase at Orchard Supply Stores (or their website). Separately, you get $10 back as a statement credit on a $50+ purchase at Big Lots brick and mortar stores (not their website).

It is important to note that while the offers expire by the expiration date shown there, the window to sign up for the offer (the simple task of pressing the “Add to Card” button) is often smaller. Some of these offers have a limited number of activations, so if there’s an offer you may need, add it to your card as soon as you see it.

If you have an American Express credit card with Membership Points (not the Blue line of cards), they have a new promotion running under the “AMEX Offers” section that went live on March 22 in 2016. You earn 2X membership points on Amazon.com purchases made with the card. The promotion is good until 7/31/16.

You must manually opt-in to this promotion. Even though it expires in four months, the window to opt-in is typically small. In other words, if you don’t opt-in, the offer won’t be shown in your account for four months. In other words, if you think you may use it, add it to your card the next time you login to your account!

Screenshot of that with the important bits highlighted can be found right below:

If you have an American Express credit card, logon to your account and check the special offers. One of the latest making the rounds is a promotion that gets you $10 back as a statement credit if you make a purchase of $30 or more at Exxon Mobil gas stations by 12/31/15. You have to manually add this offer to your credit card.

Once added, this offer expires 12/31/15. However, if you don’t add it to your card, it can disappear from the available offers at any time. This is because of two restrictions: there is a limited number of sign-ups per offer, and the offers may also have a limited runtime of their own regardless of the sign-ups. So, to summarize, when you see an offer you may perhaps use in the future, add it to your AMEX card right away!

TIP
If you have multiple AMEX cards on the same account (in other words, the same login account), pay attention to which account number you add the offer. It will only work if you use the card with the offer on it. Otherwise, no luck and customer service won’t fix it for you.

Note also that a lot of the offers are only shown to a subset of their cardholders. So you won’t have available to you every single offer you see mentioned on the internet. How AMEX decides to offer what to who(m), I do not know, it’s probably part of their “secret sauce” targeting system.
