A subtotal is a running total of part of a list. Check the subtotal, the subtotal before tax, add a subtotal row.
On a receipt it is the amount before tax and delivery, which is why the final figure is always higher than the one people look at. In a spreadsheet a subtotal row sums a group, and the grand total then adds those rather than the individual lines.
