Not sure about that particular mix, but have you checked at La Michoacana? They carry lots of Goya products. There are 2 locations that I know of, and I think I heard there is one near downtown--but the ones I know for sure are at 410 and Honey Hill (?)--it's right there off Evers by the big dollar theater, and there's one on Culebra near, I think, Reed Rd.

Also, the dreaded Wal-Mart carries Goya products--you might have some luck there as well.
