I got acroos a site with a reference from one of my colleagues in office, he had ordered a customized coffee mug with a pic of his wife and baby on the cup, the cup looked really beautiful and great finishing and what’s more that was for free only the shipping charges Rs.50/= was charged.
http://www.myntra.com/ - “Your products, your way” offers various gifts in your customized manner, click on the link and you will get to know everything from the site with its easy interface.
It allows for registeration using an E-mail Id, once you register using an e-mail, a Code will be sent to you in mail which will serve as a coupon in getting your free Coffee Mug(Customized). At the moment it allows for only free Coffee mugs, but I heard of other such schemes in the past I keep looking on this for various options, you can subscibe to its tweets to be more up-to-date.
There is a short-comings to this which few are making use for their advantage – you can register using different mail-ids and which e-mail ID you can have a free gift 🙂 atleast I managed to do it.
