In "Does Costco save you money?" (Tribune, May 25), the bar graphs comparing prices at the bulk grocery stores Costco and Sam's Club with grocers Smith's and Harmons were misleading and darn unhelpful.
Take the chart on Bush's Original Baked Beans. The visual comparison with colored bar shows that at $12 Costco is way more expensive more than six times! Harmon's under $2 price.
But then there's the fine print: Costco's $11.99 is for eight 16.5-ounce cans, while Harmons is $1.79 for one 28-ounce can the bars heights compare nothing relevant. (And doesn't Harmons sell 16.5-ounce cans, which would be a fairer comparison?)
