Mercado Livre prices
The published price starts with the base price from the central system. The Mercado Livre connection can apply one shared rule to all products.

The calculation order is percentage adjustment, fixed increase or reduction, and then rounding when configured.
For example, a base price of R$100.00 with a 10% adjustment and an additional R$5.00 becomes R$115.00 before rounding.
Product-specific rule
Product preparation can define a percentage, fixed adjustment, or final price for that product only. Empty fields keep using the connection rule. After saving, check the projected price.
