variety store

A variety store or price-point retailer is a retail store that sells inexpensive items, usually with a single price point for all items in the store — магазин, торгующий всевозможными мелочами по одинаковой цене (аналогичен нашим прилавкам Всё по 10 рублей /Всё по 15 рублей / Всё по 30 рублей)

Variety store products include cooking supplies, small tools, personal hygiene supplies, kitchen supplies, organizational supplies, small office supplies, holiday decorations, electronics supplies, gardening supplies, home decor novelties, toys, pet supplies, out of print books, DVDs and VHS tapes, food products and automotive supplies.

Consignment shops~ комиссионный магазин, комисссионка

Consignment shops get items from clients and sell them for a percentage of the profits. If you open a consignment shop, you will have less risk because you can fill your store with merchandise without paying until it's sold. Merchandise often sold through consignment shops include antiques, athletic equipment, automobiles, books, clothing (especially children's, maternity, and wedding clothing which are often not worn out), furniture, firearms, music, musical instruments, tools, and toys. eBay drop off stores often use the consignment model of selling. Art galleries, as well, often operate as consignees of the artist.
In the UK, the term "consignment" is not used, and consignment shops selling women's clothing are called "dress agencies".

A flea market -- блошиный рынок

Example: I am very interested in starting a resale/thrift shop specializing in home furnishings, tableware, women's vintage clothing, china/tea sets. (example would be "shabby chic")

I shop flea markets, thrift & resale shops all over the Cleveland, Ohio area. (There are many, but mostly charities— Goodwill, Salvation Army, etc) I want my shop to have high quality merchandise that I buy at fleas, antique & thrifts & repaint, repair (minor) and resale in a beautifully merchandised shop. Maybe the shop can have a tea room also. There is nothing like this here (that I have found), there is only one store in all of Ohio that I have found that sell the "Shabby Chic" line & it is a very upscale store in a very ritzy mall.

a huckster wagon — автолавка
... The huckster wagon was really a grocery store on wheels.

From a huckster

1) a seller of shoddy goods; cheap-jack; one who sells wares or provisions in the street; a (pack) peddler , packman, pitchman, street trader, vendor, or hawker (торговец, лавочник, разносчик, ~ коробейник)
2) One who uses aggressive, showy, and sometimes devious methods to promote or sell a product. (делец, проныра, спекулянт, барыга, торгаш )
Today the word “huckster” is likely to be associated with a type of person engaged in a shadowy scheme of some sort with the aim of fleecing others. But back around the turn of the 20th century, the word meant something quite different — a noble profession.
In those days a huckster most often referred to a person honestly engaged in the sale of edible goods to individuals supplying fresh fruits, poultry, vegetables, meats and groceries of all kinds to their loyal customers.

3) {Informal} a person who writes advertising copy, especially for radio or television advertisements (составитель рекламных роликов и программ на радио и телевидении (advertisement copywriter))

a strip mall — длинное одноэтажное здание, разделенное на секции, в которых размещаются магазины

Shopping centers are locations consisting of retail space. In the US suburban context these vary from strip malls which refer to collections of buildings sharing a common parking lot, usually built on a high-capacity roadway with commercial functions (i.e. a "strip"). Similar developments in the UK are called Retail Parks. Strip malls/retail parks contain a wide variety of retail and non-retail functions that also cater to daily use (e.g. video rental, takeout food, laundry services, hairdresser). Strip malls consisting mostly of big box stores or category killers are sometimes called "power centers" (USA). These developments tend to be low-density; the buildings are single-story and there is ample space for parking and access for delivery vehicles.

Another prominent form of retail development in areas characterized by "sprawl" is the shopping mall. Unlike the strip mall, this is usually comprised of a single building surrounded by a parking lot which contains multiple shops, usually "anchored" by one or more department stores (Gruen and Smith 1960). The function and size is also distinct from the strip mall. The focus is almost exclusively on recreational shopping rather than daily goods. Shopping malls also tend to serve a wider (regional) public and require higher-order infrastructure such as highway access and can have floorspaces in excess of a million square feet.
