How's your Prime Day been? Grab any good deals? Here's one you may be interested in: Amazon wants to give you 10 bucks to spend on anything on the site. All you have to do is buy $40 in Amazon gift cards.

To get your virtual tenner, all you have to do is click a button (here) and enter code GCPRIME2021 during checkout while you're buying at least $40 on an Amazon gift card. You can also click the aforementioned button and reload your own balance by $40 or more. Note you can only use the credit on items sold by Amazon itself — but considering Amazon sells everything under the sun, you're still free to use your $10 on just about anything.

You'll get your $10 two days after your gift card purchase. This promotion ends when Prime Day ends — that's midnight tonight, Pacific time. Use the links in the preceding paragraph to take advantage.
