You may not know what you need till you need it. You might have to purchase these things while on vacation, so save money by bringing them along in the first place. Some of these things you could need a bit of but not enough to warrant the full package price, so check out this guide, and get some packing inspiration.

Band-Aids of All Sizes
If new pumps, sandals, or sneakers hurt your feet, this vacation emergency may have you rushing to the nearest drugstore to purchase bandages. Since you probably already have them at home and don't want to buy a pricey big pack for a weekend getaway, stash enough Band-Aids (and other first-aid essentials) to last in a small container, like an empty Altoids tin.
Stock your most used painkillers in a clean, empty contact case. They fit in your purse, and you can keep the different meds safe and separated.
Oops, You Missed a Spot
Stain removers, like Tide to Go or Shout Wipes, can help with spot blotting, but if you need to clean a heavier stain, pack a tiny bit of powdered detergent in an extra plastic bottle (like an emptied, rinsed, and dried hotel sample size). It's a lot cheaper than buying a jug or box of detergent on vacation to use only a tiny bit to hand wash something.
All Bagged Out
From the quart-size for carryon to small snack-size portions, fold plastic bags of all sizes and place inside one gallon-size sack. That way you can buy larger snacks and save the rest for later or divide up for family members. It's also an easy way to keep messy stuff locked in tight or even hold a wet bathing suit in a pinch.
Vaseline Solves Everything
Vaseline is such a great multipurpose product that you can use to moisturize your lips and skin, or remove your makeup. It can also act as a soothing balm for your skin if you hurt yourself. Go generic to save more bucks!
It's Munch Time!
Bring some snacks with you when you're on the plane to tide you over before your next meal. This way, you won't feel tempted to buy the overpriced not-so-fresh snacks when you're in the air.
If you subscribe to magazines, remember to pack them in your carry-on so you don't find yourself tempted by the kiosk displays. Bring along the book you're trying to finish and another one as back-up, in case you're stuck with a delay on the plane ride home, too.
Empty Water Bottle
Liquids are a no-no when going through airport security, but there aren't rules against bringing an empty water bottle. Throw one in your carry-on and fill it up using a water fountain on the way to your gate. That's $4 in your pocket.
Chargers For Electronics
It's great if you remember to bring your cell phone, iPod, or laptop, but forgetting to pack the appropriate chargers means you might run out of juice before you know it. Just transfer the chargers from your packed luggage to your carry-on so you can use them during a long flight delay.
