Mason Jar
The glass jar with a lid (about $1.50) is one versatile item in the kitchen. And not because it makes everything from salads to soups look better (a trend we hope sticks around).

How it'll save you: Beyond canning and storing food, these containers are ideal for making and storing your own salad dressing. Load the ingredients in, screw the lid on and shake; when you've used it all up, the oil-slicked glass jar is much easier to clean and reuse than a plastic container would be, and you'll have spent much less to dress your salad than you would have if you'd gone the premade route. Plus, they're also great for whipping warm milk for a homemade latte, so you can make a $4 coffee for a fraction of the cost.
