I currently use a order dollar limit to establish shipping cost, ie: less than $75 = $4.25, less than $150.00 = zero
With the upcoming USPS price changes, I want to change to a weight based model. However, with over 1,000 products I don`t want to have to add the weight to each product individually. Products in most categories have the same weight, so is there an Add-On that I could use to do this.
