Crazy Prices Wikipedia
Crazy Prices (occasionally Super Crazy Prices) was a supermarket chain operating in the Republic of Ireland and Northern Ireland formerly owned by Associated British Foods. When Associated British Foods sold its Irish operation in the late 1990s to Tesco, the stores were rebranded to Tesco (in Northern Ireland) and Tesco Ireland in the Republic).
Crazy Prices were noted for concentration on price reductions at the expense of presentation, including the Yellow Pack brand and presenting goods to shoppers still in warehouse packaging. They were among the first supermarkets in the island of Ireland to regularly offer late-night opening - further detailed in the Tesco Ireland article.
