Last year, My Coke Rewards died a slow and painful death. It was replaced by its lesser progeny, which I simply call Coca-Cola Offers.
Every once in a while, a good one pops up. I have gotten an uncountable (okay, 5) number of movie tickets from them by doing little to nothing. Those good ones are often related to a sweepstakes. Although the offer reads that you need to enter a cap code for an entry, you usually don’t. Read through the T&C and look for the alternate method of entry. Normally, it will let you click through, sometimes up to 10 times per day, and have a possibility at an instant win without any cost, caps or otherwise.
The more you know.
