If you remember I had earlier posted on getting Free printing from different site and had also mentioned about zoomin!
Well yet again if you have not purchased before you can get 20 more (15 free if you sign-up) prints and a bigger size..
This is under a special promotion valid only upto 31 March......
How to go about:
All you need to do is get your free account here.. (On creation get 15 prints free)
If your already a member you know what to do..
> Add photos to your account.. (i.e 15 4*6 prints and 20 5*7 prints)
> Now while making payment apply voucher code ZOOMIN5x7 (that is x and not * )
And now you will have to pay only Rs.25+tax for getting 35 prints and in a days time!!
I suggest to make the best use of it coz I liked there service very much..
Create your account here......
