Bag It Today: What the heck is it? (probably a scam)

Got the readers digest sweepstake thing in the postal mail today. I really want to know who gave them my name and address in the first place 😛issed-off:

India Today group has become a one-stop shop for these shady telemarketing type of offers/deals/sweepstakes..
The group runs not less than 20+ mags and all of them have a few pages dedicated to such shit.
And NEVER ever give them your phone number or email id.
