craftgrrl | Citric Acid and Witch Hazel

I have been looking for citric acid to use to make bath fizzies for christmas presents but I am not having any luck. I would rather get it close to home before thinking about ordering online and waiting even longer etc. Any ideas? I check Michaels, Hobby Lobby and Wal Mart. I think I remember my mom using it to make lollipops when I was little which is why I tried the baking aisles as well as the salts/soaps aisles. Any info is great!

Oh and Witch Hazel too? I have NO clue where to even begin looking for that! I appreciate it!
