Basically MCRPointsPlus is a new way to use your codes. Instead of buying something cheap, you can use the codes as sort of a coupon to knock the price down a bit. For example, a DVD that would normally cost 9.99 might cost just 6.99 with as few as 42 MyCokeRewards points.
It appears that each mycokerewards point has a value of about 10 cents, which is far more value than it has over at mycokerewards.com. Checking the items at mycokerewards.com, you can find a $25 gift certificate costs you about 1000 points. Doing the math, we find that the standard mycokerewards point is worth about 2.5 cents. So 2.5 cents vs 10 cents seems like a good deal for spending your points at MCRPointsPlus, but the down side is they limit how much you can take off of each product using the points.
Thanks for the info, got any code laying around
