Living on the edge - How to save money

Because my income decreased during my futher education I had to shift the lifestyle I've incured.
So I started to analize where I need money and where it is pure luxury to spend it on.
That's why I start this serie "Living on the edge". I will describe how I saved money and will share my thought and experiments with you.

First of all I live in Switzerland. Everythin here is a little bit more expensive than somewhere else. So I was thinking about buy the expensive food and hygiene products in Germany. Why? Well hygiene products are around 1/3 or 1/2 of the price in Switzerland. But there are some problemes first how to get there...I don't have a car and with the public transport it is also expensive so I have to buy a lot that I can get the ticket price out. Another "porblem" is that I could invest the money in a swiss store so the people working there become enought money so they can life in switzerland too.
So i decided whene I visite my family who live near ther german boarder I will go and buy some stuff in germany like the hygiene products. So I can combine two things without extra costs. I would have visited my parents anyway so I could also go and buy some stuff there.
