Normally, the modus operandi of this is to induce innocent people luring them that they were most luckiest people in a draw conducted and they got prizes to claim. Hurry and collect at a designated mall. When you visit convenience store, they would ask you to fill a coupon and put it in a box. Thereafter, with all address/telephone particulars, they call you over phone and ask you to come along with your spouse. They would insist that spouse should invariably accompany you, failing, you are not enttiled to claim the prize. I was receiving phone calls like this and I told them that since I am busy I requested the prize to my residence. They did not agree. They insisted that I should personally come and collect. My wife in the meantime dropped this lucky dip affair with her friends/relatives. They cautioned her not to visit the mall under any circumstances as they would force you to sign up some membership forms for which you are liable to go on subscribing. This is rather forced sale promotion in short, the terms and conditions would not be revealed and one would be trapped. Be ware and do not attend these sale promotion holiday inducements.
