On my birthday I bought myself 2 shots. The first was 2 oz of El Mayor Extra Anjeo for $20. It was fantastic and I just purchased a bottle from here. The second was Casa Azul Extra Anjeo. It was 1 oz for $157 I can honestly say that was a huge mistake. They are flying on their reputation. Save your money this is hands down the better buy.
I believe that this is one of THE best Tequilas on the market. I will be buying more.
