Online shopping from Costco is available in California. Shopping online at Costco is not restricted to certain states, but conditions on some items do affect residents of California and other states. Costco's first retail location was in San Diego.
Certain items on Costco's website require shoppers to be Costco members before buying them, but the majority of the inventory is available to non-members. Additionally, the availability of individual items is not dependent on the shoppers' living in California.
Costco enforces California's Electronic Waste Recycling fee on sales of television and other electronics through its website. The charge occurs at checkout.
