Price calculation

[ReddySk]

Hello Guys, 

i do not know what I am doing wrong or if I understood the behavior wrong but the calculation is not working for me. 

I have a virtual product. I would like to set price 30€ per hour and minimal quantity for sale 4. Hence I expected that it will automatically calculate the product price to 30€.

Then when I will add it to cart with quantity 4 i expected price 120€. But it has still 0€. Of course the price was not recalculated neither on Pricing tab of the product. 

Another problem with calculation I have when creating bundle product. Even if I have manually added there Retail Price, the bundled product price is still 0€.

What I overlook with settings? 

I am using 1.7.5.1.

Thanks and Regards

Reddy
