Definitely checking this out. What sort of guarantee is there with used stuff? Will it come with the original packaging?
When you say that you're adding new stuff... are you a part of AnimeCastle? If so, do you, by any chance, have Volume 4 of My Otome used? I've been trying to find it everywhere for a half reasonable price.
Shipping is sort of killer, and a $75 order is a bit steep for free shipping.
