Take a moment and while staying in Bavaria, visit several outlets that are situated in the area.
Also pay your attention to that the shops work longer on Fridays, big shopping centers are open until 21, on Saturday, as a rule, the working day is shortened, and on Sunday the shops do not work, even grocery or clothes shops. Hypermarkets are closed too.
Necessarily use the system Tax Free Shopping; it will help you to save money. When you buy something (whatever: clothes, souvenirs and so on, but not food), ask for the form Tax Free, fill it in when you have spare time in the hotel (you need to fill it in with your name and surname as in your passport, the passport number and the address of your living place). Put all the things bought by the system Tax Free in one bag/suitcase!!! After the registration for the plane take this
Suitcase and show on the customs be ready to show your things if the customs officer will ask you to do it. After this you will be sent to get your money back (VAT refund).
However, take into account that this procedure can take from 10-15 minutes to 1 hour, because of the queues, so you will need a time frame. However, it is worth it because you can return nearly 14% from your purchases.
