a discount is a reduction from the amount that is owed for example we figured LG owes us $2.1 mil a determind number (based on units sold times a %) so we told them if you pay now we will offer you a discount of $.5 mil so they paid $1.6 mil.

if we ask Casio for $3 mil but they offered $2 mil and we accepted this is not a discount it is an offer and acceptance
