the problem is that garlic will turn rancid rather quickly, if you don't use all of the minced garlic within a few days. if you don't have a heavy hand with garlic in your cooking, fill the jar or container with olive oil as well, until the garlic is submerged. that will help the garlic store longer in the fridge, and you'll have garlic flavored oil to cook with
