You only got the discounts applied to one camera. Try ordering them seperately maybe?

None of that makes sense. Are you trying to add all that and come up with the subtotal?

i think its doing 10% off the whole order, then another 15% off the whole order...

rather than show it in one "DISCOUNT" part at the bottom, its showing under each camera... kinda confusing...

The sum of the two products is X
The 10% discount leaves you with 0.9X
The 15% discount is applied on 0.9X

Subtotal is 0.9*0.85*X
