Our new Fedex (priority, economy) shipping rate is quite lower than DHL express, so we are replacing DHL with Fedex. Our low cost fedex rate is not listed in webstore yet. It will be listed in new webstore to be effective in 1 or 2 weeks. You can still choose DHL in online order, we will ship by FedEx and reduce shipping fee in final invoice and payment collection. (Canadian buyers are not applicable.)
