If you have an American Express credit card, especially one like the Amex Gold, the Amex Reward Multiplier (formerly known and often still referred to as the Gyftr portal) is a fantastic way to accelerate your reward points accumulation.

Here is a look at how to use the Amex Reward Multiplier portal to potentially earn 5x reward points on everyday purchases, focusing on popular platforms like Amazon and Blinkit (sometimes misspelled as Blinkbuyt!).


What is the Amex Reward Multiplier (Gyftr) Portal?

The Amex Reward Multiplier is an online portal operated in partnership with Gyftr. It allows American Express cardholders to earn bonus Membership Rewards (MR) points by purchasing instant gift vouchers for various brands or by shopping on partner websites directly through the portal’s links.

How to Earn 5X Points: The Amex Gold Advantage

The exact multiplier depends on the specific American Express card you hold.

  • Amex Gold Charge Card: This card is particularly powerful when used with the Reward Multiplier, offering a 5X multiplier on earned points.
  • Other Cards: Cards like the Platinum Reserve, Platinum Travel, or SmartEarn might offer different multipliers (like 2x or 3x).

Crucial Note: It’s important to understand how the 5x multiplier is calculated. It doesn’t mean you get 5 points for every ₹100 spent. Instead, it multiplies the base reward rate of your card.

  • If your Amex Gold base earning rate is 1 MR point per ₹50 spent…
  • Using the 5x Multiplier means you earn 5 MR points per ₹50 spent on those specific transactions.

Step-by-Step Tutorial: Buying Vouchers for Amazon & Blinkit

The most common way to leverage the Reward Multiplier for everyday spending is by purchasing instant gift vouchers. Here’s how to do it for Amazon and Blinkit:

Step 1: Access the Portal

Navigate to the official Amex Reward Multiplier website (this is usually a co-branded site with Gyftr). Ensure you are using the correct Indian portal.

Step 2: Log In or Register

You will typically need to enter your registered mobile number and potentially the first few digits of your Amex card to verify your eligibility and view the correct multipliers for your card type.

Step 3: Search for the Brand

Use the search bar to find “Amazon” or “Blinkit”.

  • For Amazon: You will usually see options for “Amazon Pay Gift Cards”. These are the most versatile as they load directly into your Amazon Pay balance.
  • For Blinkit: Look for Blinkit gift vouchers.

Step 4: Select the Denomination

Choose the value of the gift voucher you wish to purchase (e.g., ₹500, ₹1000, ₹5000).

Step 5: Checkout

Proceed to the checkout page. The portal will summarize the total cost and the estimated bonus Membership Rewards points you will earn based on the 5X multiplier (for the Gold card).

Step 6: Payment

Complete the purchase using your Amex Gold Card.

Step 7: Receive and Redeem

You will receive the gift voucher details (usually a code and sometimes a PIN) instantly via SMS and email.

  • Amazon: Go to your Amazon account, select “Amazon Pay,” and choose “Add Gift Card.” Enter the code. The balance is now ready to be used for shopping, bill payments, or partner merchants.
  • Blinkit: Open the Blinkit app, go to your account or payment section, and apply the voucher code before checkout.

Pro-Tips for Maximizing Value

  1. Check for Processing Fees: Some vouchers (especially Amazon Pay) might occasionally have a small processing fee attached when purchased through Gyftr. Calculate whether the bonus points you earn outweigh any additional fees.
  2. Monthly Caps: Be aware of any monthly limits. Amex often imposes a cap on the bonus points you can earn per month (e.g., maximum 5,000 bonus MR points per month via the Multiplier). Check the current terms and conditions.
  3. Voucher Validity: Always check the expiration date of the vouchers. Amazon Pay vouchers usually have a long validity (often a year), but others might be shorter.
  4. Instant Gratification: Vouchers arrive instantly, making this a great strategy for unplanned purchases. If you need to order groceries on Blinkit, buy the voucher on the portal first, load it, and then place your order.

By building a habit of using the Amex Reward Multiplier for regular expenses on Amazon and Blinkit, you can significantly increase your Membership Rewards points balance, bringing you closer to rewarding flights, hotel stays, or other redemption options.
