Yes as I've mentioned in other topics every Latin Ameerican kitchen including restaurants has the Knoir or Maggi chicken powder. The 2 pound jar of Knorr Caldo con Sabor de Pollo was on sale recently at my mainstream market for maybe $6. I bought it to re-stock 
The last time i bought cubes they were in the foil wrapped cubes inside a glass jar not a box but stepmother came home with a box from discount market about a year ago. She never used them.She saw an old recipe that called for cubes. Not the sharpest knife in the drawer. . They do absorb moisture and can get sort of not goopy but bit softer, darker. Prefer powder. So many old recipes though call for the cubes as standard.
