How much money could it take for amazon.com to deliver to Sheffield, England ?
You can look it up on Amazon's site.
Amazon will tell you when you go to purchase something. But watch out, amazon has many scams on their site.
Put in an order (but don't complete it); the site will show you the shipping charges, then (if you want) you can cancel the order. I often order from Amazon, and they DO show the shipping charges before you complete the order.
