I love this article on uses for vaseline. Here are just a few of the ideas:

Feet cracked and sore? Work some petroleum jelly into clean feet before bedtime, put on socks, and wake up the next morning with soft, smooth feet. It's a lot cheaper than the fancy foot cremes available in stores. You can also use it on pets' pads to prevent damage from harsh weather conditions like snow and ice.

Keep lips kissing soft. For you who use lip balm regularly, save your money. Petroleum jelly works just as well and stays on longer. Put lipstick on underneath it for a bit of color.

Take care of squeaky door hinges. If you have squeaky door hinges, don't buy lubricating oil. Place a small amount of petroleum jelly on them and the squeak will disappear. As a bonus, it won't drip like oil.

Use as shoe polish and conditioner. Need to shine your shoes but don't have the right color polish? Just apply petroleum jelly to leather (or faux leather) shoes, then wipe and shine with a soft cloth. At the same time, it conditions the leather. You will also save money because you won't have to buy shoe polish in different colors.
