Here's finally some thoughts on how to use Crescent Shop for handling Yahoo auctions. There's another alternative, Rinkya, for handling auctions. I have not used them, but other members note that they are more expensive, only take cards, not PayPal, and charge S&H fees on every auction.
Crescent will combine S&H for as many auctions as you wish, and even for shopping orders outside auctions too. Yes, you can order Pinky stuff directly from Animate, for example, but the fees for that are higher than for the auctions (¥2-2,500 or 20-25%). See the information under Shopping Service.
http://www.crescent-shop.com/Start by reading the page Auction Deputy Service. The important thing to know is that you have to make a deposit of at least $50 before bidding. That amount is good for ¥15,000, however, which would by you many Pinkys! Another important fact is that you can bid on as many auctions that you like (within the limit of your deposit – but you can make another deposit underways, if needed). The fees for auctions are ¥1,875 (for ¥15,000) or 12,5%.
If you have not done so already, Sign Up, and Login. The first thing you see is the form for entering auction data (it corresponds to Search & Order). Copy the URL of the item that you desire and past it into the form, name the auction so you know which item it is for, and enter your maximum bid.
However, before going that far (or further), you must consider the time frame. To be on the safe side, only send auction orders that can be handled during Japanese office hours, and maybe evenings. Those few auctions that end while most people over there are sleeping should be approached earlier, if you get my point. Use the timer mentioned above to establish when an auction ends in your time zone.
Use a service such as
http://www.worldtimeserver.com/time.aspx?locationid=JP to find the current Tokyo time.
Check the progress of the auction under Ordering Status. This page should show that you have made a deposit, that a bid has been made, and ultimately, that you have won – or lost it.
When you are satisfied with your purchases, you send a shipping order, and receive an invoice for the balance with all costs specified by email. After paying, you will get a message when the package is on its way. Crescent shop uses EMS which is pricy but safe, similar to FedEx. The tracking number will be on the Shipping Status page.
That's it, please let me know if there is something you would like to add or change, and post your own experiences of Crescent shop and Rinkya.
