Have you ever heard of a site called Zazzle.com? Or maybe you have heard of the more popular version of the same thing called Cafepress.com. Either way, now you have. These websites are called print-on-demand sites offering plain products ranging from mugs, mouse-pads, t-shirts, fashionable clothing, accessories, clocks, calendars, books, CDs, etc.

Users can create their own designs and print them out for one's own use or sell them through the readily-available market place on the sites. Here are a couple of things that we, normal but geeky, folks can do with sites like that.

QR Code with valentine's day message. February is approaching and we are hacking our brains left, right and center for that special gift for our loved ones. Why not go to our QR Code creation page, create a special QR Code with a special message (perhaps, something along the lines of 'will you marry me?', maybe?) and give it to your better half? Well, if walking down the aisle is not on the cards, there's always the option of conveying a special message, an invitation to dinner, or maybe a link to your proclamation of love on your blog.

Special QR Code mug to celebrate anniversary. Well, you don't have to be single and insanely in love to use QR Code creatively. Love is a well-celebrated thing and most couples who are already well on their decades worth of anniversaries can still use QR Codes creatively. How about inviting your other half for a romantic cruise via a mug that you have created using the above-mentioned sites? As far as we can see, the price of creating and getting your own unique mug sent to you is not too expensive.

Creative, mysterious QR Code message for customers on a card mailed to their inbox. As usual, businesses are in the lead as far as using QR Codes is concerned. Give your customers something to think about (or do, like scanning the QR Code) when you mail them a special card with a QR Code printed on it. Get a good copywriter to write an enticing headline like 'The Secret Unscanned' on it to get them to scan the QR Code. Well, we are sure a good copywriter can come up with a better headline than the lame one we just posted.

Stickers and Calendars with special message on booths during exhibition. These sites offer printing of stickers as well – perfect! Print out special QR Codes on these calendars and send them out to your customers. They love free things, everyone does. But most of us, each and every one of us love a little mystery too.
