The Sam's Club on El Camino Avenue is one of 63 clubs closing nationwide after the company went through a performance review.
"We buy other things from here, oh my God, I'm shocked," said Alan Annane, a Sam's Club customer. "Everybody was happy yesterday eating pizza."
The lights were on at the Sam's Club with some employees inside, however, the store was closed for the day.
A sign out front said it is reopening Friday morning before officially closing January 26.
According to a company spokesperson, up to a dozen of the impacted clubs will be turned into eCommerce fulfillment centers to speed up delivery.
The company also said it will provide resources for employees affected and 60 days pay including severance for those eligible.
However, what surprised more people was not only the closure of Sam's Club, but the Walmart on the same block.
The Walmart will official close on February 9, according to a sign out front. Both businesses are owned by the same company.
