I am using wp-ecommerce latest version (3.6.8 RC5) and having trouble getting weight based shipping to work. Have had a few requests on the forums over there since RC3, but have not gotten a response.
Problems is that customers are charged the highest shipping rate no matter what the product weight is. For example, product weighs 14 oz., shipping for up to 2 lbs. is $2.00. Highest shipping rate listed is $30.00 for 10+ lbs. Everyone is charged $30.00.
Has anyone gotten this feature to work correctly? Any help is appreciated. Using WordPress 2.7. Thanks.
