Prices Remain High. Costco Isn't the Answer: Teresa Ghilarducci

The most recent data on inflation shows prices rose last month by the smallest amount since January, but that doesn't mean consumers are in the clear. The debate over whether higher prices will be a temporary phenomenon or here for the long haul continues. In the meantime, shoppers should know there are things they can do to deal with sticker shock.

First, remember that the headline rate - an increase of 0.3% in August from the prior month and 5.3% from a year earlier - is based on the prices of a basket of goods and services a typical consumer buys. But a look at more than 400 items tracked by the Bureau of Labor Statistics shows some prices surged a lot more than others.

The price of rice actually declined and legume lovers will be happy to know lentils also decreased significantly. Apple prices have surged about 6%, but oranges are up only 1%. Instant coffee prices barely budged, while those for roasted coffee rose more than 2%. Adjust your food shopping accordingly.

Think twice about shopping at wholesale stores like Costco. Studies show people just tend to buy more than they actually need rather than save. A more sure-fire way to cut costs when buying groceries is to stay away from foods that have been altered and then repackaged since the process can double the price. For example, plain tomato sauce is six cents an ounce, but once it's called spaghetti sauce, it jumps to 20 cents an ounce. Also, remember that inflation can be sneaky - producers may keep the price the same, but reduce the quality or quantity.

When it comes to gas, there aren't that many ways to beat the 43% price jump over the last year. But some perspective may help to soften the blow - filling up a car's tank tends to be a very small percentage of a household's overall spending. Thanks to inflation, the extra money spent on gas probably totals around $75 a month as of late.
