Costco runs membership warehouse stores that sell groceries, household goods, electronics and fuel in bulk at low margins, funded largely by annual membership fees rather than markup. It operates across North America and several overseas markets including Japan, the UK, Korea and Australia, and also runs pharmacies, optical counters, travel booking and e-commerce alongside the stores.
