Yes. Shipping costs change with your order quantity. As you add more products to your cart, shipping will be charged for each product accordingly. Shipping charges will increase minimally only as you increase the quantity of the same product (same size, same material). However, if the products are different in your cart, shipping will be charged separately for each product. Shipping also depends on the delivery address. We have a Shipping Cost Estimator on the cart page, which will show you the estimated shipping charges once you enter your zip code and select your shipping method.
