How to say "off-the-shelf" in Japanese

• レディメイド
  no-adjectiveCovers ready-made or off-the-rack goods, especially ready-to-wear clothing. It is a less common loanword, so it is seldom the word you want for off-the-shelf in general; reach for it mainly in the clothing sense.
• 市販しはんCommon
  no-adjectiveCovers the commercial sense of off-the-shelf: store-bought, over-the-counter products available to the general public rather than custom-made. This common word is the usual choice for off-the-shelf software, parts, or medicines.

Use 市販 for products you can buy in stores as ordinary commercial goods; 「レディメイド」 is much less common and mainly suggests ready-made, especially ready-to-wear clothing.
