How to give a discount according to ShipTo City of the customer?

Summary:

Do you have any documentation or do you how to give a price adjustment according to the ShipToCity of the customer ?

I.e. Customer 1 is located in city A, Customer 2 is located in city B and Customer 3 is located in city A. So the base price is $5 for item X. However, if the city of the Ship To is City A they have a discount of $0.5

Thanks in advance.
