Coca Cola has come up with a great way to make more money: Give you less Coke for more money and get you to think it's doing you a favor.

Coca Cola is branding the 7.5-ounce cans as "90-calorie portion-control mini-cans." That translates into they want you to keep drinking Coke, which you might not do if you were concerned about all 140 calories of sugar in the 12-ounce cans.
The Center for Science in the Public Interest -- the nation's food police -- shopped around for the shrunken cans and found the 8-packs selling for $3.99. That compares to 12-packs selling in the same stores for $4-$6. The per ounce price consumers are paying for the mini cans ranges from 50% more to more than double the cost for Coke in regular-sized cans.

This isn't entirely new for Coke. In 2006, the company was marketing its 100-calorie cans. The difference? Those were 8 ounces compared to the newly shrunken 7.5 ounces that weighs in at 90 calories.
