To the point American Express is monitoring cardholders - via consumption habits - trying to detect specifically... prepaid gift cards.

Prepaid Gift Card Restrictions

In the absence of the possibility to use American Express cards directly in stores (such as Costco, which only accepts Mastercard), many American Express cardholders had fallen back on prepaid gift cards.

These gift cards can be purchased directly in grocery stores or convenience stores… or even reloaded regularly, and are immediately usable.

Review on the Vanilla Prepaid Card (And an Alternative You Should Consider Instead) - myvanilla

After limiting monthly purchases in the 5 points-per-dollar categories to $2,500 for the American Express Cobalt® Card, American Express has decided to go one step further and tackle prepaid gift cards directly.

Here’s the note that’s starting to appear in cardholder statements about the Membership Rewards program:

As such, these new rules have been in force since July 5, 2019, and warn cardholders who would “abuse the program” with the aim of intentionally obtaining points to which they would not be entitled.

American Express now reserves the right to deduct points from the account after the fact.

Prepaid gift cards of the Vanilla type are clearly targeted: American Express refers to these means of payment as “easily convertible to cash”.

Gift cards linked to specific stores (SAQ, Amazon, GAP…) are not covered by this measure: these cards can ONLY be used in specific stores, unlike prepaid gift cards, some of which can even be emptied at an ATM, making them “easily convertible to cash”.

These rules apply to Membership Rewards cards:

Warnings, financial review and Amexile

In 2020, American Express closed suspicious accounts in several waves after issuing the aforementioned warnings. Indeed, customers who appeared to be abusing the points system in the eyes of American Express suddenly had all their credit card accounts blocked, and all non-transferred points were immediately lost (Privilege Points, Aeroplan Points, Marriott Bonvoy Points). These events are known as Amexile.

What’s more, the spouses of the people who were amexiled were also expelled from the American Express customer base.

In 2023, there was a lot of feedback from people who had undergone financial reviews. Others instead received warning letters from American Express about their spending habits.

Bottom Line

American Express is tightening the screws to prevent abuse of its Membership Rewards program. As far as we know, in Canada, institutions don ‘t have the technical means to know what you buy when you go grocery shopping or to the corner store (whereas in the U.S., issuers have access to level 3 transactions – whereas in Canada it’s level 2).

However, it is clear that abnormal behavior (a $500+ purchase at Couche-Tard is not usual behaviour) can be detected automatically… prompting American Express to take punitive measures on the accounts identified.

It’s a safe bet that pressure was put on American Express by merchants selling prepaid gift cards, faced with an influx of customers buying… only prepaid gift cards. The interchange fees paid (between 3 and 4%) are not profitable for a merchant if no other products are purchased in-store.

But it’s unfortunate to see here a way to close the door on being able to use an American Express card… anywhere: let’s hope that failing to close the door on itself, American Express will take the lead in convincing new merchants to accept its cards!

This is already the case thanks to the Shop Small initiative, which has gained momentum with many small retailers now accepting American Express.

You can continue to store and buy store gift cards at IGA /Métro / Super C… and earn lots of points in these 5-point/$ American Express Cobalt® Card categories! However, moderation is advised and prepaid gift cards should be avoided.

There are plenty of ways to optimize your purchases at merchants who don’t accept American Express, such as unlocking a generous welcome bonus. As American Express is a very generous issuer, you don’t want it to turn its back on you if you want to play travel hacking long-term.
