Product price is wrong when i add Specific prices and discount in group

[gdilove]

Hi, Guys ,  I have some problem when i use the default theme:

 

a test product price is $19.32

 

when i add a Specific prices  $5 Currency Units in product price

 

and add a discount 10% in Customer Group.

 

in product page the price is 12.39 = 19.32 * ( 1 - 0.1 ) - 5

 

but in product-list page , the price is 12.89 = ( 19.32 - 5 ) * ( 1 - 0.1 ) 

 

the cart and the order page , the same price 12.89 is right. 

 

why? Is that a bug ?  How can i fix it ?  Thanks!

I have the same problem in prestashop 1.5

I have the same problem too. All my products show up as £47 even though in the back end, the prices shown are correct.

I think I have a similar problem in version 1.6.1.6

I have a customer group discount and the cart discounted price showing correctly but the quantity discount price and the amount discounted is not correct

 

Example:

Original price was £ 4.36 

Customer group discount 5% = £ 4.14 ( this is being displayed correctly) 

But..

My quantity discount should be -£ 0.55 but is displaying -£ 0.52 

and the Total price should be £3.59 ( £ 4.36 - 5% group discount = £ 4.14  -  quantity discount £ 0.55  =  correct final price £3.59 ) but the cart is displaying £ 3.62

 

Anybody having the same problem 

Thank you
