Scotch Bonnets? : Where to find?

Yes, I know habaneros are easy to find and are probably 90% of what I want. I do find the scotch bonnet to be ever so slightly more "fruity". A recipe I'm wanting to try asked for scotch bonnets and usually when I'm trying a recipe for the first time, I try to make it exactly as presented before I go substituting or fiddling with it. Where may I find them in Houston?

(The recipe in question is Jollof rice, if you are wondering.)
