Boxify

To quote accurate shipping rates, your shop needs to know the size of the box to be shipped. That's easy if you always use just one size box, but most merchants use a variety of shapes and sizes. Boxify provides your shop with the solution. Use it to record the dimensions of your products and boxes. Then when a customer checks out from your shop, Boxify calculates how the order is to be packed and obtains from UPS, FedEx, USPS, DHL Express, or Canada Post accurate carrier-calculated rates.
