REMA 1000 is a Norwegian multinational no-frills soft-discount grocery chain owned entirely by the Reitan Group (Reitangruppen). REMA is a short for Reitan Mat, referring to Odd Reitan. 1000 refers to offering a selection of only one thousand different products.

A no-frills or no frills service or product is one for which the non-essential features have been removed to keep the price low. The term "frills" originally refers to a style of fabric decoration. Something offered to customers for no additional charge may be designated as a "frill" – for example, free drinks on airline journeys, or a radio installed in a rental car. No-frills businesses operate on the principle that by removing luxurious additions, customers may be offered lower prices.
