Okay when pre order, they are known to be inflating their prices quickly on demand.

I have used their discount power of 10dp which I only gotten 2% off.
This 10 dp is about a grand of stuff I bought, I found the discount pretty non existent.

For example, I buy stuff from hobby search , amiami, and cd japan, just three items from each store not costing me over a grand and I got much bigger discounts. Of course is better than none I suppose.

Ny is not a great place to get restock items as they price hike a lot. Bumble bee from 4700 goes to 7,000 easily when released. Is kind of sad.
They don't used to be like this, but they currently do this for every masterpiece.
