Dive Insight:

Amazon is challenging warehouse clubs, but doesn’t seem to be denting Costco’s numbers much, as the warehouse retailer continues to focus on its brick-and-mortar operations.

The percentage of U.S. households that pay for Amazon Prime but hold no other club membership has grown from 7.1% in 2013 to 16.2% in 2016, while the percentage belonging to just Costco fell to 9.8% from 14.9%, and households belonging to Sam’s Club fell to 9.7% from 16.9%, according to research from Cowen and Co. released last year. 

Costco is comfortable with its "offensive" e-commerce strategy, CFO Richard Galanti told analysts Thursday, according to a transcript from Seeking Alpha, adding that the retailer isn’t “really worried about what others are doing.”

“[N]ot to be arrogant or cavalier about it, but we feel good about what we are doing, we have got great brick-and-mortar comps, we are doing things offensively in our view, not defensively, and we have got a lot of things going on the online side,” Galanti said.

While partnering with Instacart, Google Express and other third-parties for online orders, the retailer keeps its focus mostly on driving members into stores and enhancing its “treasure hunt” atmosphere, he said. He acknowledged that competition from Amazon and other players, including newcomer no-frills grocery-and-sundries retailer Lidl, will indeed present a challenge. But, he said, other retailers are likely to lose more market share than Costco.

“[I]t’s traditional food retail that is getting hit more than us,” he said. “We have to keep driving our members into our warehouse and we do that with of course great prices and great items, certainly fresh foods, certainly gas stations… which brings them into parking lot, if you will, and certainly the loyalty program … all those have helped us, and then the treasure hunt,” he said. “[W]e are asked a lot about [Lidl] coming into the East Coast, they are going to take share, but they are going to take share from everybody else a lot more than they can take share from us. So we haven’t really seen a big change like people buying less at Costco because of other formats out there.”
