I am building my online shop and would want to use two of WPC plugins, the WPC Product Options and WPC Price by Quantity

I am having problems with the pricing. 

EXAMPLE 

I am selling customizable pens for 6,50€ 

the add on is the packaging which costs 2€ extra 

= in total 8€

under the product options there is the total price of 850€ for 100 pieces

THEN comes the price by quantity 

if the customer wants to order 100 pieces there will be a discount

it is ONLY showing the price of the pen without the packaging

which is 520€ (discounted) for 100 pieces without the packaging 200€

if I put them to my CART

the total is 720€

which ist 520€ discounted plus the 200€ 100 pieces packaging

which is okay 

BUT how can I remove the 2 total prices on my product page because they are showing 2 different amount

AND is it possible that the "price by quantity" applies discount with the add ons?

It would be nice if you could help

Thanks

Roseanne
