We buy our Coca-Cola products by the liter in glass bottles. Glass is cheaper than the 1.5L plastic bottles and can be returned for the deposit. We don’t drink them a lot, but we accumulate a lot of bottles over the weeks. Recently, this lady has frequented our neighborhood in search of bottles she can buy. What a great exchange! We get rid of all the extras laying around and make a little money in the process. I’m not sure what she does with them so I will ask when she returns on Saturday.
