Amazon Japan has been the way to go for me. I got the new Never Ending Limited Blu Ray box with shipping to the USA for $93 USD. I also pre-ordered the new Babymetal Blu Ray and got it for around $60 USD with shipping. Amazon Japan is the way to go from the USA unless it includes some pre-order bonuses such as posters. Anything not attached to the normal package is not received in my personal experience however others may disagree. CdJapan and Yesasia are both reliable options but are definitely more expensive however you will get pre-order bonuses assuming they are available still.
As for Tenso, I have a lot of experience shopping from Asmart and have used them but don't love them. I don't like that they ask you to make a copy of your ID and send it to them however I did and haven't had any problems over the last couple because of it. They are expensive but they do offer pretty reliable service from what I've seen. I know package consolidation is available but i've never taken advantage of it although I think it's kind of pricey as well. Overall they have been a good service but for the price, it should be. It's also nice that I can make real time bids on my own on YAJ.
CD Japan might not be the cheapest, but they're still pretty reasonably priced. Their shipping is awesome, too. I like them a lot.
From my experience, cdJapan shipping is only reasonable if you do not buy multiple items. It seems the more items you add to your cart the more expensive shipping becomes. As an example: One one of my last order, I ordered about $105 worth of items and shipping came to just about $75 EMS. I removed a few items (these were all MCZ CDs or Quick Japan books) and it was about $50 worth of items but the shipping suddenly dropped to about $20. I'll only order from cdJapan if its 1-3 items now. The shipping rate is more reasonable for fewer items. I'm from California, if anyone was wondering.
Is there any way for me to join the fc even though I live in te U.S.? Like give them my tenso.com address or something? They sell the best stuff to fc only :(
The Osaretai one is better than the hako oshi one imo, but if you couldn't get one of the previous giga lights and your favorite members aren't Momoka or Reni-chan, then the hako oshi one is for you in terms of official goods.
