For a single guy, a Costco membership can look a little ridiculous at first. Why pay an annual fee to buy enough toilet paper to outfit a small office when there is only one person in the household? But Costco can make financial sense for a solo shopper when the purchases match his lifestyle, especially when he regularly buys gas, household staples, meat, electronics, prescriptions, or other items that Costco sells at competitive prices.
The bigger question involves more than whether Costco has cheap groceries. A membership only works when the savings beat the membership fee without encouraging a shopping spree that wipes out those savings. That makes the real calculation surprisingly simple: spend intentionally, buy things that actually get used, and resist the siren song of the 48-pack.
