Provide EXACTLY ONE — a request with neither, or with both, 400s. Each override REPLACES the base catalogue price for its (store, sku) while active. For the resulting sellable price a till uses, read `GET /products/:id/units?store=` instead. ## OpenAPI ````yaml /openapi.json get /v1/store-prices openapi: 3.0.3 info: title: Solya POS API version: 1.0.0 description: >- The Solya POS backend HTTP surface.
