What NOT to Buy at the Drugstore

It never occurs to me to do my grocery shopping at the drugstore -- although my local Duane Reade pharmacy has recently been making a strong push for it by expanding its food aisles and adding ready-to-eat meals.

But it turns out that plenty of people do find it convenient to one-stop-shop -- and they're paying for the privilege, according to a new survey.

ConsumerWorld.org, a consumer education web site, just conducted a pricing survey in the Boston area, tracking 25 common grocery items -- both foods and household products. It found the average drugstore charged 50% more than the least expensive supermarket: $102.94 vs. $68.55 for the basket of goods studied.

Stores in the survey included: Walgreens, Rite Aid, CVS, Stop & Shop, Shaw's and Market Basket. (An earlier MoneyWatch package found a more nuanced set of choices for CVS shoppers: Cereal and bottled water were no-nos, but milk was actually cheaper than at the supermarket.)

Among the drugstore chains, Rite Aid proved the priciest, with the 25 items adding up to $107.96; CVS was the least expensive, at $98.12. Meantime, among the supermarkets, the receipt from Shaw's had the biggest total at $83.56, while Market Basket had the lowest at $68.55.

Here's a breakdown of some of the wide price comparisons from the survey:
