Hi ,
I have product options (checkbox) with extra amount .
Now when I select that checkout box in the product page . It still display the same price in the product page ,but it is showing the correct price in the cart apge.

Ie
if price =$100
checkout =$10

Now ,If i select the checkout ,then price of the product in the same page need to show as $110 instead of original $100 itself.

So that customer will aware of the what price they will need to pay for this product in total.

Got it?
Is there any free module or how/where to change this ?
