What is the difference?

[ThomasSensei]

Hello,

Please could someone explain the difference between these two sentences?

- "many cacao beans are sold at an unfairly low price."
- "many cacao beans are sold at unfairly low prices."

I believe that both sentences are correct but I'm unsure if there is a difference or not and why.

Any help is greatly appreciated.

Both are grammatically correct.

The difference lies solely in the number of different prices that may be involved.
