Tango show tickets are one of the most "intermediated" (is that a word? ***) products/services in Buenos Aires. The problem is that while the rack-rates are inflated (to include commisions to guides, drivers, etc.), its highly unlikely that a tourist that goes directly to the box office will get a discount.

The only way to get a break in price is to go through one of these third parties that get commision, and negotiate with them to share their cut. It does add another issue to the planning, but as Ive said its highly unlikely that the box office will give you a break, unless you are purchasing a very large group of tickets.

*** what I mean by this is that there are various middle-men in the sales process
