Dworsky bought 25 common items at the drug stores and the average total price was just under $103. When he purchased the same items at the grocery stores, that total was about $75.

“You have to be a comparison shopper. Not every price at the drug store is gonna be ridiculous, but some are,” said Dworsky.

Another example? Maxwell House coffee was $6.99 at Walgreens. At Market Basket, the sale price was only $3.49

So, the study seems to prove that groceries are more expensive at drug stores. But, consumers seem willing to pay the higher price in the name of convenience.
