Pets: According to the American Pet Products Association, the average dog owner spends $1,542 annually, while the average cat owner spends $1,183.
Beverages: The average U.S. household spends an estimated $850 annually on soft drinks, for a total of $65 billion on soft drinks alone. A total of $101 billion was spent on beer in 2010.
Shoes: Estimates for what the average woman spends on shoes range from $370 per year ($16,410 over 67 years), up to $25,000 over a lifetime.I take issue with that last one. First, the shoe data have to be horribly skewed, meaning that a small proportion of women are spending a lot of money and it's driving up the average. Of course, this may be true for many of the averages on that list. The second problem I have with it is that they only list the average for women. Do men not buy shoes? And if so, is $400 a year excessive?
