Different shipping costs for different postcodes

Someone please clarify for me. Would it be possible to instead of free shippping to set a flat delivery fee for certain U.S. zipcodes? Can anyone tell me waht that code would look like.
Thanks for any help!

Hi all,

I have face problem with similar but something different can you help me?
Allow an option to add a separate price option for all of the postcodes outside of the Melbourne. Also all postcodes within 200 km of the middle of Melbourne automatically get free shipping.



Opencart Version 1.4.9.3

Thanks,

As stated earlier in the thread, you'll need a shipping method that supports postcode limitations, like Formula-Based Shipping. For the distance limitation, you'd need to specify the postcodes yourself.

Hi my website currently has a flat rate shipping for the whole of the UK. at £4.50 I would like to make free shipping to my local area by postcode (cv37) i have tried copying the forumlas in this post into the free shipping file but it doesnt work infact you cant check out im getting an error. Is there a way for me to use this? currently the free shipping is enabled and set for free on orders over £40. i havent enabled shipping by weight.
