Used good in the context of "Refurbishment (electronics)"

This is a list of the world's best-selling albums of recorded music in physical mediums, such as vinyl, audio cassettes or compact discs. To appear on the list, the figure must have been published by a reliable source and the album must have sold at least 20 million copies and certified at least 10 million units (the equivalent of a diamond certification by the RIAA). This list can contain any types of album, including studio albums, extended plays, greatest hits, compilations, various artists, soundtracks and remixes. The figures given do not take into account the resale of used albums. Certified copies are sourced either from available online databases of local music industry associations or a country with an established certifying authority (see List of music recording certifications).

As a result of the methodology that the American and Canadian certification-awarding bodies (the RIAA and Music Canada respectively) use, each disc in a multi-disc set is counted as one unit toward certification, leading to many double albums on the list—such as Pink Floyd's The Wall and the Beatles' The Beatles (White Album) —being certified with a number double the number of copies sold there. Such albums have the certifications for the number of copies (not discs) shipped indicated. Conversely, the American certification level for double albums that fit onto one compact disc, such as the Saturday Night Fever soundtrack reflect the actual number of copies sold. In 2016, RIAA included streaming in addition to track sales and album sales based on the concept of album-equivalent unit for certification purposes, and certification therefore no longer reflects shipment alone. For example, in the update of the certification for Their Greatest Hits (1971–1975) by the Eagles in August 2018, the album was certified 38× Platinum (increasing from the previous 29× Platinum certification in 2006) based on the new criteria, making it then the album with the highest certification in the United States.

A flea market (or swap meet) is a type of street market that provides space for vendors to sell (generally previously owned) goods. This type of market is often seasonal. However, in recent years there has been the development of 'formal' and 'casual' markets which divides a fixed-style market (formal) with long-term leases and a seasonal-style market with short-term leases. Consistently, there tends to be an emphasis on sustainable consumption whereby items such as used goods, collectibles, antiques and vintage clothing can be purchased, in an effort to combat climate change and fast fashion.

Flea market vending is distinguished from street vending in that the market alone, and not any other public attraction, brings in buyers. There are a variety of vendors: some part-time who consider their work at flea markets a hobby due to their possession of an alternative job; full-time vendors who dedicate all their time to their stalls and collection of merchandise and rely solely on the profits made at the market. Vendors require skill in following retro and vintage trends, as well as selecting merchandise which connects with the culture and identity of their customers.

A second-hand shop is a shop which sells used goods. Secondhand shops are often part of the different parts of the reuse or Circular economy. Different formats of second-hand shop exist, selling in different formats and type of content: from antique stores, to consignment, and various types of thrift or charity shop, where the used goods are sold.

The format of selling second hand goods in a shop, is not ubiquitous: the cost of operating a physical location alongside the need to handle large inventory, sometimes means that resellers opt for temporary venues like Flea market, garage sales or temporary pop-up type sales.
