I realise this is a long shot but I can't be bothered with ebay and otherwise they'll just go to waste. I accidentally ordered double copies of サムライチャンプルー (recced here). The extra copies are still in their plastic and everything. They were 1080円 together plus the same again in shipping, about $30 Australian. I'd be happy to sell them for A$15 including whatever it costs to send them within Australia.

Seriously I'm moving house so they'll be thrown out if I don't sell them. If you have paypal and are interested I can probably send them for cheaper than an online store even if you're overseas.

Edit: Sold

I'm very interested, just sent a PM.
