On this site, every Circle K station is in Northern Ireland. Circle K is a large petrol station chain owned by the Canadian group Couche-Tard, and it is much bigger in the Republic of Ireland.
Almost all Northern Ireland Circle K stations are run by local independent retailers. You'll often find a Centra, SuperValu or Spar shop, or a family business, with Circle K fuel on the forecourt, so opening hours, the shop and payment options are set by each retailer.
Circle K's Extra discounts are advertised in euros for the Republic of Ireland, so don't assume they apply in Northern Ireland: check at the till.
