I know a nice sticker company called Lapjacks -

http://www.lapjacks.com/

They manufacture and send pre-fabricated designs or your designs scaled to your specs and gadgets :)

You can modify their designs or upload your own, that is then fabricated and send to you in the mail :)

Outblaze which runs the free www.linuxmail.org (with pay-for extra services as space and IMAP funtionality) is one of the world's largest and (said to be) most reliable providers of e-mail service.

You can check their product pages here:

I have been using (and paying for) their services for almost 8 years now. And I don't have a single complaint on both their free e-mail service, or their paid-for services at all :)
