Question: Which store in London was an early version of the type of store that Dealz is classified as?

Context paragraphs:
Dealz: Dealz is a chain of discount retail stores predominantly in the Republic of Ireland and Spain, offering a range of general merchandise products, the majority of which are at the fixed price of €1.49.  Since the Irish rounding of cash transactions on  28, 2015 (2015--) , the company now sells its goods at €1.50 which doesn't make much of a difference in their net income due to the one cent difference.

Stanhope body: Stanhope is an archaic car body style characterized by its single bench seat mounted at the center, folding cloth top, and a dashboard at the front.  All Stanhopes featured tiller steering, either in the center or at the side.  Features of the car included a foot button to signal a bell (early version of a horn), hard rubber tires, wood trim, and eight forward speeds, three backs and a top speed of about 50 miles.  The body style disappeared by the vintage vehicle era.  It could be considered a specific type of runabout.

Hagfish (album): Hagfish is the self-titled third studio album by the American rock band Hagfish, released in March 1998 on Honest Don's Records, a subsidiary label of Fat Wreck Chords.  The album was reworked following a long delay with the band's previous label, London Records, who rejected the band's initial offering and eventually dropped the group.  Bill Stevenson and Stephen Egerton would both reprise their roles as producers, having previously worked with the band on "Rocks Your Lame Ass".  An early version of "18 Days" (originally titled "New Year's Song") and a live version of "Twisting" previously appeared as b-sides to the "Happiness" promotional single in 1995.  Alternate versions of "Hand" and "Agent 37" later appeared on the compilation album "That Was Then, This Is Then" in 2001.

Department store: A department store is a retail establishment offering a wide range of consumer goods in different product categories known as "departments".  In modern major cities, the department store made a dramatic appearance in the middle of the 19th century, and permanently reshaped shopping habits, and the definition of service and luxury.  Similar developments were under way in London (with Whiteleys), in Paris ("Le Bon Marché" in 1852) and in New York (with Stewart's).

Chadwick Square Diner: The Chadwick Square Diner or Worcester Lunch Car Company Diner #660 or Ralph's Chadwick Square Diner is an historic diner at 95 Prescott Street (rear) in Worcester, Massachusetts.  Although the building faces Grove Street, it is attached to one of the 19th century Washburn and Moen Works buildings which fronts on Prescott Street.  The diner is a rare early version of a streetcar-inspired design, and may be the only one of its type in the state.  It is 40 ft long and 14 ft deep, with twelve window bays.  It has a monitor-style roof with clerestory windows, and entrances at the ends under roof overhangs.  The northern entrance now serves as an emergency exit, while the south entrance now serves as the main entrance to the nightclub in the attached building.  The interior is exceptionally well-preserved, retaining many of its original finishes.

Loving Cup (song): "Loving Cup" is a song by the Rolling Stones,which appears on their 1972 album "Exile on Main St." An early version, with a completely different piano intro, was recorded between April and July 1969 at Olympic Sound Studios in London, during the "Let It Bleed" sessions.  (This version of the song—or at least part of it, spliced with another outtake—was released in 2010 on the deluxe remastered release of "Exile on Main St".)

Cubic chess: Cubic Chess is a chess variant invented by Vladimír Pribylinec beginning with an early version (named Echos) in 1977.  The game substitutes "cubes" for the chess pieces, where the four faces of each cube display a different chess piece (pawn, knight, bishop and rook), two blank are orientated to the players.  The symbol of king and queen are only on one side of the cube.  This provides an efficient means (rotating the cube on a square) to change a piece's type.

Camlock (electrical): A camlock is an interchangeable electrical connector often used in temporary electrical power production and distribution.  The most common form is the "16" series, rated at 400 amperes with 105 °C terminations.  Also in common use is the "15" series ("mini-cam"), rated at 150 amperes.  A larger version is made denoted as the "17" series with ratings up to 760 A.  A ball nose version and a longer nose standard version exist-the latter is the most common.  Another version is the "Posi-lok" which has controlled interconnection sequencing to a panel and a shrouded connector body.The early version original connector was hot-vulcanized to the cable body;later versions use dimensional pressure to exclude foreign material from the connector pin area;the tail of the connector insulator body is trimmable to fit the cable outer diameter.

Táin Bó Flidhais: Táin Bó Flidhais, also known as the Mayo Táin, is a tale from the Ulster Cycle of early Irish literature.  It is one of a group of works known as Táin Bó, or "cattle raid" stories, the best known of which is "Táin Bó Cúailnge".  "Táin Bó Flidhais" survives in two forms, a short version from the Old Irish period and a longer version found in the 15th century Glenmasan manuscript, which is held in the Advocates Library in Edinburgh.  It is believed to be a copy of an earlier manuscript from the 12th century.  The early version of "Táin Bó Flidhais" predates the "Táin Bó Cúailnge".  It is named for the heroine of the tale, Flidais.

Wardian case: The Wardian case was an early type of sealed protective container for plants, an early version of the terrarium.  It found great use in the 19th century in protecting foreign plants imported to Europe from overseas, the great majority of which had previously died from exposure during long sea journeys, frustrating the many scientific and amateur botanists of the time.  The Wardian case was the direct forerunner of the modern terrarium, Vivarium (and the inspiration for the glass aquarium), and was invented by Dr. Nathaniel Bagshaw Ward (1791–1868), of London, in about 1829 after an accidental discovery inspired him.  He published a book titled "On the Growth of Plants in Closely Glazed Cases" in 1842.
