Era o fue?
Hey guys, I am still a bit confused regarding the difference between "era" and "fue" even after reading many articles. Therefore, I would like to get some help from you guys.
We all know that era and fue can both be used and are grammatically correct(depending on the message that you want to convey), for example:
1. La clase fue interesante.
2. La clase era interesante.
So here comes my question. The scenario - I went to the supermarket yesterday and bought some fruits. My friend is asking me how the price was.
In this case, can "era" and "fue" both used?
1. El precio fue barato.
2. El precio era barato.
If yes, can I assume there is a connotation behind each usage?
1. El precio fue barato.(The price was cheap when I went, and now it is not)
2. El precio era barato.(The price was cheap when I went, and I don't know if it is still cheap or not for now)
Muchas gracias con antelación!
