I wanted to buy the AstroGaming Halo 5 special edition A40 headset since it is 20% off. I went on their website, A50 special edition (John 117) is 20% off, but not the A40.
Please I don<t know if it is the right place for this, but fix it 
Topic close… I found out that their link was not pointing to the A40 with 20% off (It might also be a bug) and for me in Canada, the US website was just not functioning.
