I'm trying to retag some questions (such as this one) on the Board Game Stack Exchange, and the only good tag I can think of is "Selling".
But that seems inefficient, and a word that covers both buying and selling would be more useful to the site. The first word I thought of was transaction but that doesn't seem to cover it.
Someone has suggested to me business, but again it doesn't sound like it works in the context.
Is there not a single word (or a phrase shorter than 25 characters) for this?
My first thought when I saw “buying and selling” was trading (independently of coleopterist. The verb trade covers both bartering (trading when both parties put forth goods or services) and buying/selling (trading when one of the parties puts forth money).
In context, this seems to be specifically about evaluating the price. I believe the term generally used in this domain is appraisal; valuation or pricing are used with a similar meaning in other communities.
The word you seek is 'commerce'.
The role of procurement (one of the professional terms for purchasing and selling) is to find a sustainable supply of goods at a reasonable price.
Arbitrage may be the word you are looking for.
