After much debate we decided the average cost of a roll of paper towel is $1.00-$1.20. By searching the web we learned that the average family uses at least two paper towel rolls a week. Larger families can be known to use even more. A good wiping rag in the kitchen will last for at least a year, or more if washed correctly. So if you eliminate the use of absorbent paper from now on you will definitely save some money in the long run.
If you are not convinced about switching, at least pick a paper towel brand that is environmentally responsible or uses recycled products to make their paper towels.
