System 76 computers has been doing this for some time now, I got my stickers sent last year.
Here is the address you can send a self addressed stamped envelope to receive them for free.
United States
System76, Inc. (Free Sticker)
1582 S. Parker Rd. Ste. 310
Denver, Colorado 80231
They sell computers (laptops, desktops, and servers) with Ubuntu pre-installed or no operating system. Their prices are very reasonable, and don’t include the dreaded “Microsoft tax”.
So, go on, send them an envelope, get some stickers, let the world know that Windows is not the only option.
[update] Thanks for Digging.
