Just heard from WtFrostyCakes, there is a mailing proxy called JaponicaMarket.com that’s offering 50% off until end of the year. That means 400 yen for one AUCTION item from Yahoo Auctions JP, which is very cheap. Basically it’s half as cheap as Yokattaweb.jp (they charge 700yen + 10%) and over 3 times cheaper than Tenso.com (they charge 1500 yen).
But there is more:
1st item is 400yen. 2nd item 200yen. 3rd item 100yen if from the same shop or same seller! Has to be same seller if using yahoo japan auctions.
The reason why you would want to use Yahoo Auctions, is because that’s where all the Comiket-exclusive and Dream Party-exclusive stuff is being listed(short of attending these events yourself).
Also check out some tapestries and daki from Tsuki ni Yorisou Otome no Sahou, the new Navel game.

Pretty sure you can pay Japonicamarket.com 400 yen to order one of these (600 for two and 700 for three.)
