If you’ve ever had to pour wine down the drain because it’s gone bad before you had a chance to drink it, then you know it’s a sad, sad moment. To prevent that happening in the future, make a small investment in one of these vacuum wine sealers.

It removes the air from an opened bottle of wine and can extend the life of your bottle for up to a week! This $8 set includes one vacuum pump and two sealers. Even if you only use it to save two half bottles of wine, it will have already paid for itself. Plus, they make great stocking stuffers for adults.
