When does Action-HQ charge your card for a preorder? Is it right away or when the item is released? It is for Masterpiece MP-05 Megatron. http://www.action-hq.com/store/product_info.php?products_id=2625
They've also stated they'll charge immediately for Clear Alt Mirage and the order is un-cancellable. I found that out when I pro-ordered without properly reading the specifics. I've paid for something that won't be seen until September.
I think if you do paypal, they charge right away... if you use thier CC page, they wait to withdraw till they have stock of said item, I think....
