Be EXTREMELY careful with the NRD's now. As SSC will no longer refund you if you don't like the figure upon shipment. I bought the Mark III, didn't like it and returned it and they kept the NRD.
I've bought a couple of figures that I didn't like when I received and returned them. I USED to get the NRD refunded with that but it seems like they sneakily have changed that. I looked at their website for clarification but it's worded extremely vague.
I think it's a bit ridiculous for Sideshow nickel-and-dime their customers. If they feel that they need to keep my money even when there are issues with the design then I will take my business elsewhere and suggest you do the same. So it's not worth pre-ordering. Most of the items don't go to Waitlist and if they do it will most likely convert.
Also, I discovered that if I ordered and returned an item that was in-stock that previously had an NRD they would refund the full amount. That is even more proof of the need to not pre-order.
