Shipping Zip Code

Hello,



I know that when customers get shipping estimates it takes the zip code from store information (admin/company) is there a way to change the zip code so that it takes different one then the one that is displayed in the company information? Reason I need this is because I’m shipping items from a supplier that is few states away and its giving me lower shipping for states that are more away from them ex my company location. Please let me know if I can change this.



Thank You
