Yes @Aqua-Resin I have ben wondering the exact same thing. Our eccommerce has a variety of products ranging from a lightweight item that takes a huge box (dimensional shipping costs) and little flat items like lighters and candles, since we use the carrier calculated costs.
I would love to be able to charge one shipping price (bulk) because at this point, it would charge the customer 3 times for three boxes when in fact I could ship them in one box, and also add a free shipping if added to, etc.
@paul2009do you think would this ever be a feature that could be included or addressed by squarespace in an effort to enhance their ecommerce U.I. ?
