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:

I Know Things Sweatshirt (Rs. 1,250) with 10 days left to buy

I Know Things Tee (Rs. 750 ) with 10 days left to buy

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!
