Amazon’s October Prime Day officially “Prime Big Deal Days” this time around is live right now, running October 6 through 7. It’s shorter than the usual four day summer event, just 48 hours, but Amazon is still dropping new deals three times a day at midnight, 8am, and 1pm Pacific. If you’re planning to buy anything in the next two days, which card you pull out of your wallet actually matters more than you’d think.
Here’s the breakdown of which cards earn you the most back, and a couple of things worth knowing before you start adding to cart.
The Obvious First Choice: The Amazon Prime Visa#
If you’re a Prime member and shop on Amazon regularly, the Amazon Prime Visa is built specifically for this. It earns 5% back on Amazon.com and Whole Foods purchases for Prime members, which is a meaningfully higher rate than almost any general cashback card offers on a single retailer. There’s no annual fee beyond your existing Prime membership, and the rewards post as statement credit or Amazon gift card balance, depending on how you set it up.
Worth noting: Amazon has been running a promotional bonus on this card some cardholders have seen offers up to 9% back through the end of September, so it’s worth checking your account for any targeted offer before Prime Day starts, since those bonuses don’t apply universally.
If you don’t already have this card and are a frequent Amazon shopper, Prime Day week is actually a reasonable time to apply you’d want to factor in the approval and card arrival timeline, but if you already have it sitting in your wallet, this is exactly the event it’s designed for.
If You Don’t Have the Amazon Card: Flat Rate Cashback Is Your Next Best Bet#
Not everyone wants a store specific card, and that’s fine. A solid flat rate cashback card typically earning 1.5% to 2% back on everything is a reasonable fallback that still beats paying with debit or a card that earns nothing extra.
The gap between 5% (Amazon Prime Visa) and 2% (a generic flat
rate card) is real money on a big ticket purchase. On a $500 purchase, that’s $25 back versus $10 a $15 difference on one order. If you’re buying multiple items across the two day event, that gap adds up fast.
Check for Rotating Category Bonuses#
Some cashback cards run quarterly rotating categories that occasionally include online shopping or specific retailers like Amazon. If your card has an activated bonus category this quarter that covers online retail or department stores, it’s worth checking before Prime Day you could be sitting on a bonus rate you’d otherwise miss by defaulting to your usual card.
A Few Practical Things to Keep in Mind#
This event unofficially kicks off holiday shopping. Amazon knows this, which is why you’ll see deals on gift cards, Advent calendars, and seasonal decor alongside the usual electronics and home goods. If you’re planning to get ahead on holiday shopping, the cashback math above applies just as much to gifts as it does to things you’re buying for yourself.
Electronics deals come with a caveat worth knowing. A lot of this event’s deals lean on Amazon’s own devices Echo, Fire tablets, Blink and Ring cameras alongside general electronics. If you’ve been following the broader tariff situation we’ve covered elsewhere on this site, it’s worth remembering that electronics remain one of the categories most exposed to ongoing tariff costs, which is part of why retailers like Amazon lean so heavily into deep discounting events like this one to move inventory and keep demand up despite higher underlying costs.
Don’t let the rewards rate talk you into buying things you don’t need. A 5% cashback rate is a real discount, but it’s still only a discount on money you’re spending. If a $200 purchase wasn’t on your list before this sale, getting $10 back doesn’t make it a net positive for your budget it’s still $190 out of pocket for something you weren’t planning to buy. Use the cashback math to optimize purchases you’d already decided to make, not to justify new ones.
Set a spending cap before you start browsing. The three times a day deal drops are designed to create urgency and keep you checking back repeatedly. Deciding your budget before the first deal drop rather than in the moment is the simplest way to walk away from this event having actually saved money instead of just spent it.
The Bottom Line#
If you’ve got the Amazon Prime Visa, this is the two days it was built for use it for anything you buy on Amazon or at Whole Foods during the event. If you don’t, a solid flat rate cashback card is a perfectly good fallback. Either way, the real savings come from combining the right card with purchases you’d already planned to make not from letting the sale talk you into spending more than you intended.
