Battlefront did a bit of switching around boxes and blisters for Flames of War and wanted to let you know when things would be back available on the website.
From the update:
Earlier this year we turned off a number of our Early War and Late War box codes as part of our ongoing range management. A large number of these items were available in blisters or via the Special Order Catalogue immediately, whilst some have taken a bit longer to return. We have noticed that there has been some confusion in the forums regarding how to get hold of some of these items, or when they be in stock so we have created this listing of codes and ETAs.
