RRP and MSRP both describe recommended selling prices, but the terminology and context differ. For online stores, the key point is that a recommended price is not automatically your own previous selling price.

Make it clear when a price is a manufacturer or supplier recommendation. A recommended price is not automatically a price your own store previously charged. That distinction matters for price comparisons and discount claims.
