The Los Angeles Times found consumers of products from soap to cereal are not getting as much soap and cereal as they used to.
Some companies are using creative packaging techniques such as dimpled jars to sell shoppers less product at the same price.
"I think that's very deceiving," she said.
It's not just cereals -- the makers of Skippy peanut butter started putting a larger dimple on the bottom of the jar, making less room inside for their product. But the price has stayed the same.
"I don't really think that's fair," Dallas shopper Kate Thompson said. "I mean, they should let you know if they put less in there and they're charging you the same."
The makers of Dial soap cut contours into their bars, cutting the size.
The company told the Los Angeles Times is trying to save cash because the raw materials for making soap are rising in price.
"Well, I'll start looking at the packaging more, for sure," Conway said.
Some shoppers said they will continue to buy their favorite brands, regardless of the price, but other people said they will opt for generic products.
