The Card Every Amazon Prime Shopper Should Have Before October 7

It's official: Amazon's Prime Big Deal Days is happening Oct. 7-8, and this will be one of the best times of the year to score major discounts if you're a Prime member.

But here's an additional hack to score an even bigger discount… Pair all your shopping deals with the Amazon Prime Visa (see rates and fees). It has a $0 annual fee and gets you 5% cash rewards on Amazon.com, Amazon Fresh, Whole Foods Market and on Chase Travel purchases with an eligible Prime membership.

Personally, I got the Prime Visa a couple months ago. Here's why I recommend all Prime members should carry it.

Earn 5% cash rewards on Amazon and Chase Travel

Most rewards credit cards earn you just 1% to 1.5% back on online purchases, including Amazon. That's a decent discount, but it's not exactly mind-blowing.

Now imagine getting 5% cash rewards on every Amazon cart, every Whole Foods haul, and every travel booking through Chase Travel.

That's what the Amazon Prime Visa delivers -- as long as you're a Prime member.

Here's the full breakdown of rewards:

• 5% cash rewards at Amazon.com, Amazon Fresh, Whole Foods Market and on Chase Travel purchases with an eligible Prime membership
• 2% cash rewards at gas stations, restaurants, and on local transit and commuting (including rideshare)
• 1% cash rewards on all other purchases

That 5% back really adds up -- especially during Prime Big Deal Days when you might be doing some bulk buying.

For example, a $500 shopping cart earns you $25 in rewards. You can use those rewards on future Amazon checkouts, or redeem for a statement credit.

Oh yeah, there's a $0 annual fee. So all the rewards you earn are pure upside.

Get a $150 Amazon Gift Card instantly

The Prime Visa also has a quick and easy welcome offer for new applicants.

Get a $150 Amazon Gift Card instantly upon approval exclusively for Prime members. There's no minimum spending or any hoops to jump through. As soon as you're approved, the credit is applied straight to your account.

If you're planning to shop during Prime Big Deal Days this October, this is the easiest way to knock $150 off your total. And yes, you can use it during Big Deal Days as long as you're approved before the event is over.

Prime Big Deal Days October and beyond

This card isn't just a one-hit wonder for Prime Big Deal Days. You'll want to keep using it year-round and set it as the default payment for all Amazon purchases.

If you spend about $100 a week on Amazon, you're looking at roughly $260 per year in cash rewards (much better than the measly $52 you'd earn with a standard 1% cash back card).

Now tack on the $150 Amazon Gift Card you get instantly upon approval, and your total first-year value jumps to $410 -- without changing any of your habits.

And that's not even counting the extra earnings you could get from using the card at restaurants, gas stations, or when booking travel through Chase Travel. Even if you only use the card for Amazon purchases, the value speaks for itself.

Don't miss the window

Since Prime Big Deal Days land on Oct. 7-8, it's smart to apply now so you have the card locked and loaded in time.

If you wait too long, you might miss the window to get the welcome offer and use it during the deals. And trust me, that $150 + 5% back combo is too good to pass up.
