1. Mail in your dull Tweezerman tweezers, nippers, and scissors to be sharpened for FREE rather than buying new tools.
2. Reduce food waste and save $$$ with this DIY baby food that can be eaten right away as a puree or frozen for later.
3. If you're in college, research textbooks on Amazon to score a better deal than at your local student store.
4. And if you must take notes in your textbooks, write them down on these ruled sticky notes instead so you can easily sell back the books.
5. Plan some delish no-cook meals so you have a lower gas bill and won't have to crank your AC to compensate for a hot kitchen.
6. Time to upgrade your sheets? Swap in this microfiber set that's super soft, washes well, and oh-so breathable.
7. Forgo goo-fighting products by removing stickers using stuff you already have, like vodka, olive oil...you get the gist.

8. Ditch aluminum foil and keep stuff fresher for longer with these stretch silicone lids -- especially if you're constantly using half a can of chicken stock or tomato paste.
9. Embrace the annoying pop-up messages while you're online shopping and ask the "person" on the other end about any deals or discounts to apply to stuff you were already dead-set on buying.
10. Try out a roll of bamboo paper towels you can toss in the washing machine and reuse 120+ times.
11. Sell your old books, CDs, games, tech, and other stuff to Decluttr to, well, declutter your stuff for a profit.
12. Sleep better — even in economy! — with a nuzzling neck pillow that costs less than a flight upgrade to a better seat.
13. And if you're traveling somewhere with a beach, skip pricey suits and buy a few inexpensive suits to give your beach looks some variety.
14. Put kitchen scraps to work (again) by making flavored olive oil with leftover herbs, deodorizing shoes with green tea bags, and other savvy ideas.

15. Opt for some cheap, chic sunnies to get you through the remainder of summer activities instead of shelling out big bucks for designer glasses you'll lose on a water slide.
16. Cut down on your oil-blotting sheet use by blotting with (unused!) toilet-seat covers so you can look all breezy and put-together like SJP in a transitional movie scene.
17. Educate yourself on basic household skills -- instead of calling a repair person when you have a section of carpet that needs replacing -- with The Useful Book.
Blotting your face with toilet-seat covers, unclogging your own toilet, and selling your old iPhone adds up, folks.
