Prices have been dropping fast in the US. I've got a line that I sell there at the same price as the ones you mentioned above. Shipping is rough some times but then again its a weight.
If you are looking to save on shipping drop me an email and I will see if I can get you a better price than what appears as my default shipping rate on my site.
