Rest of requirements: 1) if maunafcturer is not choosen then discount is added for all products

2) if there are 2 ranges for example 0-100 cart value has discount 10% but for Manufacturer A in range 0-100 discount is 12% than discount for manufacturer (12%) is more important. Bellow is strategy: ◦

Manufacturer A - 0-100 cart value - discount for example 10% ◦

Manufacturer A - 101-200 cart value - discount for example 12% ◦

Manufacturer A - 201-300 cart value - discount for example 14% ◦

Manufacturer B - 0-100 cart value - discount for example 13% ◦

Manufacturer B - 101-200 cart value - discount for example 16% ◦

Manufacturer B - 201-300 cart value - discount for example 19% ◦

Rest products NO manufacturer set - 0-100 cart value - discount for example 3% ◦

NO manufacturer set - 101-200 cart value - discount for example 5% ◦ NO manufacturer set - 201-300 cart value - discount for example 7% 3.
