I visited Costco and Dollar General to compare prices on staple grocery items.
Costco had lower prices on most items, which customers must buy in bulk.
A few items were priced lower at Dollar General, including orange juice and chicken broth.
Costco is a big-box store that sells bulk groceries at discount prices.
Shoppers must purchase a Costco membership, which ranges from $60 to $120 a year, to access the store's deals.
With inflation reaching a 40-year high, grocery shoppers are trying to find the best deals.
I compared prices per unit of grocery staples at Costco in Rochester, New York with a nearby Dollar General location.
Dollar General expanded its grocery offerings in recent years, and the chain says it can maintain low prices by keeping stores small and relatively bare-boned, ultimately offering fewer products than larger competitors.
