# Prices and price selection

A variant can have several price records.
Thor selects an eligible price for the request's currency, price channel, country, customer groups, and time.
This supports market prices and customer-specific pricing without duplicating the product.

## Define the audience of a price

Every price has a money value and tax behavior.
Optional `channelId`, `countryCode`, and `customerGroupId` narrow its audience.
`validFrom` and `validTo` control the price's validity window.
An omitted dimension describes a broader price; it is not the same as assigning a particular channel or group.

Keep schedules and scopes intentional.
For the same variant and context, use non-overlapping validity windows when replacing a scheduled price.
Do not build business rules around whichever overlapping record happened to be created last.

## One variant, two buyers

A lamp may have a base EUR price and a separate EUR price for a wholesale group.
An anonymous buyer cannot be treated as a wholesale customer just because a browser parameter contains that group's ID.
Use authenticated customer context and render the selected price returned by Thor.

## Price selection is not currency conversion

Requesting another currency requires an eligible price in that currency.
Do not relabel an EUR amount as DKK or apply a frontend exchange rate and treat the result as a checkout price.
A missing price is a configuration or eligibility state, not a zero price.

## From product page to cart

Use matching store, price channel, currency, and country for discovery and cart creation.
On catalog prices, `value` is the original amount and `discountedPrice.value` is the reduced amount when present.
For current-price display, use `price.discountedPrice?.value ?? price.value`.
A cart returns its own calculated prices and totals.
After customer or market changes, refresh commercial data and verify the cart before continuing checkout.
