SPEND $80, GET $20 OF AMAZON CREDIT: As of August 18, you can get a $20 Amazon credit when you spend $80 or more on qualifying Procter & Gamble (P&G) home essentials at Amazon.

Let's be real: One of the hardest parts of being an adult is constantly having to restock on essentials that cost a fortune. I mean, I can't go to Target without spending $100, and somehow I only ever have some paper towels and dog treats in my hand when I walk out. But there is a way you can save a little bit of money this week while restocking your must-haves.

As of August 18, you can get a $20 Amazon credit just for shopping P&G essentials. The catch is that you have to spend a minimum of $80, but with the price of paper towels these days, that shouldn't be too hard of a task. All you have to do is add at least $80 of qualifying items to your cart and you'll receive the $20 credit after purchase.

You can shop products for babies, cleaning, health and wellness, beauty, and much more. Here are some of the items included in the promotion (and there are plenty more to check out too):

• How to properly clean your groceries
• Misfits Market: An eco-friendly grocery delivery service that's good, but could be great
• Marty the grocery store robot is a glimpse into our hell-ish future
