Is there other site for buying?
I think catalog is simply an one-man company.
Yes, his goods are cheaper than others.
But, be warned, you won't really get what you
have ordered. It might be out of stock and
Ikuo-san then asked you to order other films
after you've paid the $$.
Even everything is fine, it's really slow...
Again, it's an one-man company...
Don't expect too much.
