The review looked at Walmart, Target, Staples, Amazon and King Soopers.
"King Soopers was the cheapest across the board basically because they have been extremely aggressive in their sale pricing and this back to school season," said Fry, found of uGrocery.
A 24-pack of Crayola Crayons, for example, rang up to $0.49 at King Soopers, but as pricy as $2.49 at Staples and Amazon.
King Soopers, a Kroger company, did fall short in some supply areas like paper folders and erasers. In those areas, companies like Walmart took the advantage.
Ultimately, with a shopping list of 28 items, King Soopers won out by more than $5 over its closest competitor — Walmart. King Soopers' cart rang up to just under $40. Walmart rang up to nearly $45. The most expensive carrier turned out to be Amazon at $85.
Fry recommends if you're still doing some last-minute shopping, to compare prices to find the cheapest.
"I recommend people compare prices, they take their shopping list, they look at and use apps like the uGrocery app to compare prices in real time," Fry said. "If you don't want to use uGrocery, you can look at the store website, at the realtor websites."
