I presumed there was a sell-off of the older Block Erupters to make room for the new ones announced by Friedcat, the same goes for the blades.
I think I may have jumped the gun and presumed those threads were related.
Sorry for messing your thread.
No problem.
*edit* I see your link, I'm not sure how to answer that question, that particular reseller is U.S based though and seems to sell so many he gets a huge discount, but also adds large international shipping fees to the order (and custom fees on that). Anyway, I'll ask YXT... and get back to you.
*edit* the offical eu reseller (yxt) thread says 0.57 https://bitcointalksearch.org/topic/official-asicminer-block-erupter-europe-246020 as does his shop http://www.asicminer-shop.de when you buy 50 units or more.... will update when I hear back from yxt.
