eBay or Middle Man?

[omably]

Hello All!!~

I've noticed on eBay that the prices of Ayu's AT08 Goodies are way overpriced then those advertised on mu-mo and other websites selling the goods in Japan. However the shipping of the goods are free. Just wondering what would be better, buying the goods straight off eBay or using a middle man and buying them off mu-mo (if you still can > <) Also what would be quicker and more reliable?

Thanks!!
