Shipping Rates for Products less than 1 pound
How do I modify shipping rates for products that weigh less than 1 pound?
Using USPS Priority
What do you want to change the shipping to for items under a pound?
The Shipping rates are returned from USPS based on the total weight of the items added to the cart.
PowerStore does include a way for you to adjust the shipping rate returned, you would need to own eCart to be able to modify the shipping rules.
i'm sorry, nevermind; instead of using shipping weight = .x, you have to enter 0.x
