Does any one know what this abbreviation means?

Question

I am looking at a menu in Spanish. It uses the abbreviation 's/m'. On the English version, it says 'd/m'. I found out that 'd/m' probably means 'depends on the market'. So what I'm wondering is, what does 's/m' mean?

Ex:

Pescado del día......s/m

Pescado a la sal......s/m

Cochinillo (por encargo)......s/m
