Summary
The advertisement says that BigFoods has figured out which items their shoppers buy most often. BigFoods then picked out some of those items, and compared the cost of that sample to the cost of the same items at Grocerytown, where they cost 10 percent more. The sample also used the regular, non-sale prices at BigFoods.
Strongly Supported Conclusions
Based on this advertisement, we can conclude:
Some items cost at least 10 percent less at BigFoods than those same items cost at Grocerytown.
Some of the items that cost less at BigFoods are among those items most purchased by BigFoods shoppers.
