Coffee is not my thing, the need for morning caffeine not withstanding. Thankfully, coffee has many other uses as detailed by Stephanie Rogers in 20 Unusual Uses For Coffee:
Spoiler Alert! My favorites:
Repel Fleas: Rub used, damp coffee grounds through your pet’s fur after bathing to repel fleas without questionable, likely-toxic chemical treatments. If nothing else, it will at least improve that post-bath wet-dog smell that gets all over your furniture.
Reduce Cellulite Pricey cellulite creams almost always have one major ingredient in common: caffeine, which supposedly enhances fat metabolism, reducing the appearance of these fatty pockets under the skin. To make your own coffee cellulite treatment at home, mix warm used coffee grounds with coconut oil and rub it onto your skin in circular motions for a few minutes before rinsing.
Fertilize Plants Acid-loving plants will thank you for sprinkling your used coffee grounds around their roots. Azaleas, blueberry shrubs and rhododendrons are just a few of the plants that flourish when treated with coffee thanks to all those nutrients. You can also dilute the leftover coffee in your mug and pour it right into your potted plants (as long as you don’t use cream and sugar, of course!).
Those seem like expensive uses for Starbucks.
