Coca-Cola is jumping on the bandwagon.
The Wall Street Journal reports the beverage maker is trying to lure in new customers and appeal to penny-pinching, health conscious ones by adding a 12.5-ounce bottle for 89 cents to its repertoire.
The company is also cutting the price of its eight-pack of 7.5-ounce cans.
Pepsi also has smaller sized bottles of soda for sale.
Of course, the smaller sizes may cost less, but overall, you're paying more per ounce.
