+If you seldom use discounts, applying manual discounts might be the
+easiest solution for your Point of Sale.
+
+You can either apply a discount on the whole order or on specific
+products.
+
+Apply a discount on a product
+=============================
+
+From your session interface, use *Disc* button.

+currently selected and the discount will be applied.

+=======================
+
+To apply a discount on the whole order, go to :menuselection:`Point of
+Sales --> Configuration --> Point of sale` and select your PoS interface.
+
+Under the *Pricing* category, you will find *Global Discounts*
