Hi,

Here is the situation with the shipping process, how can I adjust the shipping weight/pricing accordingly?

When ordering more than 1; each frame weighs 16 ounces, each packaging weighs 8 ounces (we can fit 2 frames per box ... so it's 24 ounces for 1 frame, 40 ounces for 2 frames, 64 ounces for 3 frames, 80 ounces for 4 frames, etc).
