May one mention prices (shem damim), measure names (shem midah), or running totals (sekum) when requesting items from a shopkeeper on Shabbat?

ShabbatCommerce

Synopsis

The Mechaber forbids mentioning prices, measure names, and running totals. The Rema permits mentioning prices and measure names for items with known, fixed prices — only running totals (sekum) are universally forbidden. Acharonim dispute the Rema's leniency.
