BUG: promotion discount not reflect in quantity discount list

Create a promotion for $1 discount off a product. The product cost $6.95. So with $1 discount, the discounted prices is $5.95.



Before promotion:



Price: $6.95



Our quantity discounts:

Quantity 2+ 5+

Price $6.50 $5.95





After promotion:

The products page shows:



Old price: $6.95

Price: $5.95

You save: $1.00 (14%)



Our quantity discounts:

Quantity 2+ 5+

Price $6.50 $5.95







Quantity discount doesn’t reflect the correct price when there is a promotional discount. Because of these, it looks like it’s more expensive to purchase higher quantities.



However, when I added 2 qty into the shopping cart, the shopping cart does reflect the correct price.
