Reminder: Just one day left in this campaign!

It has been exactly one month since our last clever Insiders tee shirt for Windows Central. This month we're celebrating a combo of Halo 5 and Windows 10 Mobile with a minimalist Cortana tee-shirt!

The shirt comes in five color choices ranging from bright blue to dark grey and there are three styles to choose from, including:

  • American Apparel Crew - $20
  • Gildan 8oz Heavy Blend Hoodie - $38.99
  • Teespring Women's Premium Tee - $22.99

All proceeds go to supporting the site including the development of our new universal app, which is nearing the public beta stage. So help our community and also grab a fun Cortana shirt that will certainly raise an eyebrow or two. (Remember, we don't get the full cost of the shirt as Teespring takes the majority).

Update + India: For those in India, you now have two options available for special pricing in that country:

The sale is only going for nine days (November 15) so make sure to get your order in before then otherwise they are gone for good. If not 100% satisfied you can return the shirt for a full refund or exchange.

Order your limited Cortana 'I Know Things' tee from Teespring now

Shipping is worldwide ($3.99) although stay tuned as we're doing our usual India-only offer too to keep costs down in that country.

From the Windows Central team of writers, thanks and we hope you enjoy it!
