The small jars are really inexpensive, less than $2. You can usually find it in the produce section, near the real thing. Sometimes you can find it on the spice isle.
For those of you that go through a lot of garlic, you can also get it in a pretty big container, pint or quart or somewhere in between. It is also relatively inexpensive.
I use this garlic in almost anything that calls for minced or chopped garlic.
