Amazon is once again offering a Free $10 credit for purchasing a $40 Gift Card. Amazon had a similar offer earlier this month, but even if you redeemed the previous offer you can still do it again and get another $10 credit with this new offer. To get your free $10 credit, visit this page and click the yellow “Apply code to your account” button. Then buy any Amazon gift card of $40 or more. To ensure you did it right, look for the following message at checkout: “Your purchase qualifies you for an Amazon.com credit. A $10 promotional credit will be automatically applied to your account and emailed to you within two(2)days.” You can technically enter promo code “GCPRIME2021” at checkout instead of clicking the yellow apply button and can reload your credit balance instead of buying a gift card, but it seems that clicking the apply button and buying a gift card is the best way to ensure the deal works, so I suggest doing that. It works fine if you buy an eGift card and enter your own email address, which is what I did.
