A ticket to a bullfight in the afternoon should cost you no more than twice the face value. Prices go down right before kickoff, so you might want to be patient. Ticket prices vary. The bullring is full of peña members, so expect a lot of drunk, friendly people. Don´t forget to bring a sandwich for halftime. It´s a tradition.

Don´t forget to buy some churros en La Mañueta (in the old part near the market). This will be their 130th year. Expensive, but good. Expect a long line.

As someone mentioned earlier, there are lots of pickpockets. Camera bags included. Don´t be lazy.

Pamplona is expensive but prices go up even further during the fiestas. Expect to pay €2 for a caña in a normal bar. Just guessing. Often better buying the liter bottles of beer in small shops. Bar service is generally impossible.
