Should I study in a small town instead of city to keep costs down?

I grew up in a huge city and have always lived in a city. I prefer to study in a city but
I saw this video about studying in a small town versus a city (i.e. London) to save money. Is the sacrifice worth it?

Or is the difference in cost outweighed by fewer opportunities (i.e. part time jobs) in a small town?
