I go to Mexican markets often and I've noticed that their dried herbs cost much less than dried herbs at other super markets. I grew up with my dad using oregeno, dried basil, red pepper flakes and all of those wonderful things, but he too bought the kind from Mexican markets that come in a cellophane bag, rather than a plastic container. For example, a plastic shake bottle of dried oregeno cost nearly four bucks at Walmart, but the very same thing in the "ethnic" aisle cost fifty cents.
Does anyone know why they are so much cheaper? Are they of a lesser quaility?
