I definitely don't recommend it. I bought 12 all day tickets, payment was charged but the tickets never came to the app. I have a bank statement and an app statement, I have complained about the situation three times via email to two different addresses, no one bothered to even reply. Better to buy tickets at the outlets, not on the AMTS app. AMTS is a very untrustworthy company (besides the fact that buses never arrive on time and even skip an entire line.
