Bitwise Worksが今月23日から25日にかけてArcaOSのディスカウント販売をするそうです。
先日、決済方法をPayPal以外でもできるようにしたそうなので、ArcaOS以外(OpenOfficeやPMView Pro等)でもいいので、こちらで購入してあげると、OS/2界の縁の下の力持ちなBitwise Worksを応援できていいのではないかと思います。

Black Friday

From 23rd November until 25th November 2018 we have ArcaOS with discount in our shop. ArcaOS is between € 17 and € 29 cheaper. The discount depends on the ArcaOS version. We recommend everyone to use the commercial version, as it includes more support options and a 12 month software subscription.
Our webshop already awaits your orders.
As a sidenote: with every order in our shop you help building the future. As we have more money to spend and so we can port more software.
