"Gillette Faces New Attack From an Old Razor Rival" by Sharon Terlep,Wall Street Journal, May 24, 2017, abridged.

Another razor rival is taking a cut at Gillette.

Edgewell Personal Care Co. maker of Schick, the No. 2 U.S. brand, is mounting a direct challenge to the Procter & Gamble Co. unit with an online subscription service that sells blades that fit on a Gillette handle but cost less.

The price for blade refills on the new service ranges from $1.78 to $3.33 per cartridge depending the type of blade and number of refills in the package. Gillette's online subscription service sells a five-pack of refills for its Mach 3 line for $2.60 per cartridge and a four-pack for its pricier Fusion line at $5.36 per cartridge with the fourth shipment free.

The move comes as P&G is scrambling to ward off competition from online razor startups and cheaper competitors. Gillette's share of the U.S. market, close to 70% in 2011, fell to 54% last year, according to Euromonitor.

A Gillette spokeswoman said the company produces higher-quality blades. "Razor technology is a matter of micronsand how every single component comes together matters," she said. Men "shouldn't have to choose between convenience, flexibility, quality and value."

Edgewell, with a $1.4 billion shave business globally, is late to the online game. Dollar Shave Club launched in 2012 and Harry's followed shortly after, both offering cheap blades and an alternative to shopping for razors in a store. P&G's Gillette has had an online service since 2014 but the shave-club business remains dominated by Dollar Shave Club and Harry's.

"We didn't think there was an advantage to just throwing our products out there; we needed to provide something that's unique," said Edgewell spokesman Chris Gough. "It's not a secret that the shave clubs have not made money, and we need to make money."

Edgewell said it would target what it considers a weak point of Dollar Shave Club: an inflexible delivery plan that leaves many men with a stockpile of blades.... Edgewell will allow customers to order as infrequently as once every nine months.
