Puis and Ensuite

What is the different between the words "Ensuite" and "Puis" they both mean "Then", right? In what context would one use both of these words? Thanks

Both words have the same meaning and are used in the same context. If you don't want to sound repetitive you can alternate between the two, for example: je suis allee en ville pour faire des courses, puis j ai prie un cafe, ensuite je suis rentree a la maison.
