I usually use HMV Japan as they have quite good discounts and is usually cheaper than Yesasia even after adding the shipping. They use EMS, so it's fast and you can track the parcel too. I tried Amazon Japan for the SHB DVDs as they give better discounts than HMV. Their shipping rates are fixed so it might be cheaper to order from them if the items are heavy. Amazon use DHL for their international shipping. My DVDs reached me within 1 day. :)
