I wasn’t at Comic Con London but Base.com clearly were. The retailer put on range of big anime discounts on some popular titles. It’s the sort of deal you hear about when it’s too late and kick yourself.
Good news; either by accident or by design, this Friday evening, the special Comic Con page is still alive. The deal page being live this long after Comic Con may be part of a plan as Base.com has pre-orders for both Horizon on the Middle of Nowhere s1 & s2 as well as Attack on Titan.
