Same product, different attributes, different prices. Price reduction only for one?

[lachos]

Dear all,

I have one product with three different sizes (eg. 10ml, 20ml and 50ml).

The problem is with implementation of an eg. "15% off" offer for only one size of the product.

I can apply such offer only for all sizes (so for one category as far as I understand).

 

I would appriciate any help.

Thanks in advance and best regards,

Paulina

Hi,

thanks for the reply.

In the attached pic you can see that you have 5ml or 10ml to choose. 

I want to make an offer that when the customer takes eg. 4 products from 10ml, then the 4th one will have the price of eg. One cent. (3 + 1 offer). This works.

Unfortunately, when the custmer takes 3x 10ml + 1x 5ml, Presta reduces the price of the 5ml to one cent.

I want to know how I can tell Presta to differenciate the volumes, so the offer will be valid only for one kind of volume.

Thanks in advance!

each capacity is a different combination

you can then set price and discount by combination
