Store displays discounted price AND $ off after coupon applied

Steps to replicate

1. Create product(s) $5.00

2. Create discount and coupon (10% off)

3. Put item(s) in cart ($5.00)

4. Apply Coupon

5. View Cart

Cart displays the following:

Product(s)        Price
Product1         $4.50
           Total Price: $5.00
           Discount    $-0.50
           Order Total: $4.50

6. Go back to product page for ordering more stuff. Price displayed on product page is now the coupon/discounted price = $4.50.

7. Add item and check cart:

Cart displays the following:

Product(s)        Price
Product1         $4.50
Product2         $4.50
           Total Price: $10.00
           Discount    $-1.00
           Order Total: $9.00

What's confusing to users is that the total of the displayed products does not add up to the "Total Price" displayed in the cart. More confusing if some products get the coupon discount and others do not.

I think it would be less confusing to users if the module added a field/column to the cart view that had the original, non-discounted price because right now the sum of prices displayed in the cart does not add up to the value displayed next to the title "Total Price"
