Solved! Go to the solution
One of the biggest conversion killers will be the shipping cost. You have to go right through to see your shipping costs. I would advise an app like "estimated shipping cost" this will show your customer his estimated shipping cost based on IP address location automatically on the product page.
Free app that requires no code to add. It did wonders for our conversion rate on www.fensport.co.uk where shipping prices can vary so much!
