Hi, I just made a cart to test the shipping on IWM site and put the 2 word of black Omni Packs and the shipping to me was 26$, I just find it too expensive for my taste if I want to buy from the direct source. Puerto Rico is part of the US and our default mail carrier is USPS, so why so expensive? Do people have the same issues? If so, any other way of ordering these models?
