10.30 offered today on Florida, north side of Cordoba. On the east side of Florida is "Edificio Thompson" about a 100 feet north of Cordoba; walk down the stairs and there is a round counter with a gentleman. He'll quote you the day's price. Sometimes one can get a slightly higher price by using one of his touts in front of "Edificio Thompson", and they take you down the stairs to the same counter and man. I've made several transactions and never received a false note. In a pinch, it's convenient.
