Well I've always full paid up until this Apoc as my first Flex, and I've always been first batch up until Superman. Then again I think a lot of statues I've ordered didn't really have batches in this current sense. But up until Superman my observation has been FlexPayers talking about when their last FlexPay will be while I've already had my shipping notice and am waiting for arrival. It just seemed like Flex we're always later than when I got my statues.
I kinda dig the installments so I flexed Thor, Hulk and Catwoman. Gives me 4 pieces to see if I get them 1st batch or later compared to how I was always first batch for every full pay I've done, exception being Superman, who apparently I'm not even 2nd batch although I'm a day 1 order.
BTW, XM: DoFP was AWESOME! I have one friend so far who didn't like it but it's my favorite X-Men film so far...we all know better by now but stay til the end folks!
