Powerquery: Filtering rows by minimum value in column B, from subsets in column A

Hello all,

Thank you for reading. I am currently trying to remove rows of a table in powerquery based upon minimum values in a column. Here is an example:

Item Price
Apples 1.99
Apples 2.99
Apples 3.99
Bananas .50
Bananas 1.00
Bananas 2.00


I need the final result to be
Item Price
Apples 1.99
Bananas .50

I think this will require a column with a custom function in powerquery, but am not sure how to go about doing this. I am fairly new to this kind of data processing.

Thank you!
