Selected 0-20% in reference to my total spend on robots* during 2013. Local purchases were only Metroplex, MP Soundwave and the BH Terrorcons.
My total spend dropped drastically (more than 2/3) from 2012's total spend as 2012 was more spent chasing up individual Classics/Henkei releases I missed out on via eBay. Aside from paying hefty after-market prices, I also spent loads shipping (quite sickeningly, say the worth of two Encore Fort Max!) them from individual sellers rather than buying in bulk (most of the time it wasn't an option).
If Hasbro does manage to bring Generations IDW figs locally, at the lowest retail sale prices they won't be able to beat BBTS' $50 plus shipping (and currency conversion) on a Wave Set of 4. I'm only shipping my POL once it brings the shipping per unit (based on an individual order rather than number or items or weight) to roughly $12-14.
As none of the local stuff has caught my interest for this coming year so far, this trend will most likely continue.
* In reference to all the purchases made to expand on my Classicsverse - which for 2013, was heavily invested in 3rd party pre-orders.
