One more, if you're up for it:
I ship around the country but offer free delivery within the city of Portland, OR (multiple zip codes). Is there a way to allow customers within Portland to skip entering a zip to allow for a shipping calculation on zero?
On the topic, is there a way to fully run through the e-junkie purchasing process (like a customer) without having to buy anything? I'd like to be able to test this out through a customer's eyes.
