We have small business and we deliver goods to only specific postcodes.How can i restrict purchase to only those postcodes.I have read that i can do it from shopping cart rules.So,I created one rule for postcode from shopping cart rules but I don't know from where i can add my postcodes and how to apply that rule to shipping and stop purchasing in other postcodes. Please help.
