Sale Coupon Fixed Price

This module extends the coupon and promotion features in Sales. When you configure a coupon program or an automatic promotion, you now have an extra reward option called Fixed Price.

• In the program form, choosing Fixed Price shows a new Price field where you enter the unit price to apply. The usual reward product and discount type fields are hidden for this reward type, so the form stays simple.
• When a matching order is created or updated, Odoo automatically rewrites the unit price of the eligible order lines to the fixed price you set. Which lines are affected depends on the program's discount target: the cheapest product, specific products, the whole order, or products matching a domain.
• Fixed-price programs can be applied automatically without a promo code, and the module checks dates, company and other common program rules before applying them.
• The reward description shown for these programs is simply "Fixed Price".

It works together with coupon.program, coupon.reward and sale.order, and is configured from the same coupon program screen used by the standard coupon app.
