Customers from USA unable to purchase from my store

Hi,

I have a store set up in canada. I have shipping zones for the USA turned on, and rates for items entered. However when customers try to check out they get a message saying “This order can’t be shipped to your location. Contact the store for more information.”

So what have I missed?

eshipper.com has shopify plugins and US pricing, worth checking

Thanks - but thats shouldn’t be the solution. I have another shopify store that works just fine without plug-in’s but can’t for the life of me figure out what setting where could be limiting my ability to sell to the USA.
