We can get garlic powder, that really is a fine powder, plus dried garlic like the above pictures, plus granules that are 2 to 3 times bigger than the above pics. I don't like the powder form as it just doesn't taste like much to me, besides the fact that I'm not used to using it. It was bought by mistake, just grabbed the container without really looking and it was the wrong one.
They also have the onion powder form I noticed. Not going to try it since I don't like the garlic powder, but it's there. We keep the onion granules and flakes in the pantry.
Somebody mentioned you don't need the dried forms to make Cajun food. Most of the recipes we make use the dried forms in the spice mixes, as well as fresh. I think the dried forms add flavor without the extra volume and wetness, also mentioned previously, of the fresh forms.
