VAT calculated wrong when more than 1 item of same product ordered

[Ralf Skirr]

Item with 19% VAT.

Price without VAT is 0.29.

 

Customer orders 20 pieces.

Price without VAT is 5.80

 

Now the shop should add 19% VAT of 5.80, that is 1.90.

 

But instead the shop calculates 20x0.35, which results wrongly in 2.00 VAT instead of 1.90. 10 cents too much.

 

Any way to fix this?

 

Thanks,

Ralf
